EXECUTIVE SUMMARY

Thirty years ago ‘bottled water’ barely existed. Nowadays the product forms an essential

business by its stable and still growing market – locally and globally. Bottled water can be

described as any product, including natural spring or well water, taken from municipal or

private utility systems or other water, distilled water or any of the foregoing to which

chemicals may be added and which are put into sealed bottles, packages or other

containers, to be sold for domestic consumption or culinary use.1

In 2012 the global bottled water market is forecast to have a value of $94.2 billion, an

increase of 41% since 2007. This increasing trend reveals that the product meets the

demand of countless consumers. And this, while the study of literature is still lacking in a

clear and definite assumption regarding the health and safety theories of bottled water.

Therefore the question arises: what factors are related to the consumers’ buying behavior of

bottled water?

This research examines two categories of influencing factors of the consumer buying

decision process of Kotler e.a. (2008): demographic (personal) and psychological factors.

More specific, the researcher tests if there is a relationship between the factors ‘gender’,

‘age’, ‘education’, ‘income’, ‘beliefs’ and ‘perception’ and ‘consumers’ buying behavior of

bottled water’.

The results of this research have shown that there is a small relationship between the

‘income’ and ‘perception’ of the consumers and their buying behavior of bottled water.

Regarding the income, people with a relatively high income and students/other young people

(16-25 years) are the most frequent users of bottled water. Despite their low income,

students/other young people are frequent users of bottled water because they are assumed

to be more sensitive to advertising and socially accepted and luxury products.

Furthermore, the more positive the perception of consumers of bottled water is, the more

they use the product. For more than ten years now, bottled water is being presented as

healthy, safe and pure. These (misleading) efforts have resulted in a positive -

pschycological- effect. Especially in comparison to tap water, bottled water scores an overall

high perception and positive beliefs of consumers. Despite the fact that consumers perceive

both tap and bottled water as safe and reliable for consumption, bottled water is seen as

‘higher qualified’, ‘safer’, ‘healthier’ and ‘a product with a better taste’ than tap water.

Furthermore it is ‘good available’ and ‘convenient’. Logically, enough reasons for consumers

to use bottled water.

It can be concluded that both demographic and psychological factors are related to the

buying behavior of bottled water to some extent.

Therefore it is recommended that bottled water producers/marketers should focus (more) on

these consumer groups, since they seem to be the target groups of the product. However,

since only demographic and psychological factors are investigated, further research with

other influencing factors is recommended to gain more insights. Finally, all bottlers of water

should be controlled by a separate institute to guarantee the quality of the product and

prevent misleading advertisement.

Consumers’ buying behavior of bottled water – Manisha Durga

CHAPTER 1 Introduction

1.1 Research background Research and studies regarding consumer attitude and behavior are generally a common

approach in post-war marketing contexts in order to establish or acquire insight knowledge

to guide marketing activities regarding the buying behaviors of individuals. Complicated it is,

but understanding buyer behavior is central to marketing management. Just as marketing

ends with consumption, so marketing management must begin with understanding

customers. 2

Due to Bottled water industry under pressure but drinks growth to be robust of Ferre (2009),

bottled water consumption has been growing exponentially since the past decade. This

growth takes place globally, but particularly in North America and Europe. The bottled water

industry has literally created its own water culture. For example, when one enters a

supermarket or a restaurant in any country of the world, one is bound to find at least a few

different brands of bottled water.

Bottled water can be defined as any product, including natural spring or well water, taken

from municipal or private utility systems or other water, distilled water or any of the foregoing

to which chemicals may be added, which are put into sealed bottles, packages or other

containers, to be sold for domestic consumption or culinary use. 3

Just like any other consumer product, bottled water requires thorough research regarding

consumer buying behavior to guide present and future marketing activities. This is especially

so, given the circumstances that the bottled water market is considered as one of the fastest

growing markets in the beverage category.

More specifically, the market was the second largest commercial beverage category in the

United States in 2008, surpassing fruit juices and sport drinks and only behind carbonated

soft drinks.4

The global increasing trend in bottled water consumption is continuing for almost ten

successive years now.5 Figure 1.1 below shows this trend during a five-year former period.

From this figure it can be concluded that the Compound Average Growth Rate (CAGR) from

this period is 10.6% and the global consumption increased with nearly 50% in 2002,

compared with 1998.

More recently, in 2008 the global bottled water consumption grew 4.5% to 218 billion liters,

according to a new report from drinks consultancy Zenith International.6

Figure 1.2 shows the global bottled water volume share in 2008 by region. North America

was the largest market for more than five successive years in both volume and value.

However, throughout the last years some other countries are showing to overtake this

position (see section 2.2.3). Although many are probably assuming that bottled water is a

luxury product, the increasing trend of the business is also seen in developing countries.

In brief, both the global and local bottled water market are becoming an essential part of the

beverage market. This remarkable increase raises several questions and is therefore one of

the drivers of this research.

Although there is a general understanding by consumers of bottled water that the product is

better in some or all aspects, there are studies (Ferrier, 2001; NRDC, 2008) which

concluded that this is not always the case. This raised several questions, mainly focusing on

why do customers prefer to choose an often more expensive and less comfortable product.

Studies stress several factors which determine the choice for bottled water. However, due to

another study (Doria, 2006) surveys usually come up with two main reasons: dissatisfaction

with tap water (especially taste) and health/risk concerns. But to what extent are these

factors applicable to the Surinamese market? And which (other) factors determine the

buying behavior of consumers toward bottled water in Suriname?

1.2 Research problem, research questions and objectives Kotler, Armstrong, Wong and Saunders (2008) argue that consumer purchases are

influenced strongly by cultural, social, personal and psychological factors. Consumers’

perception and buying behavior of bottled water in Suriname is not fully understood.

Researches and studies regarding the Surinamese setting in this area can namely not be

found. Therefore, the Surinamese market will be sampled as a relevant and accessible

segment to investigate the following research problem for this research:

Are demographic factors as well as psychological factors related to the buying

behavior of bottled water?

Essentially, this study argues that both demographic and psychological factors are related to

the buying behavior of bottled water.

To answer this research problem, the two following questions are being researched:

1. To what extent is there a relationship between demographic factors and bottled water

buying behavior?

2. To what extent is there a relationship between psychological factors and bottled

water buying behavior?

4

FHR Lim A Po Institute for Social Studies – MBA 5 - 2010


The objectives of this research are therefore:

To identify if demographic factors are directly related to the buying behavior of bottled

water; demographic factors are considered by this research to be directly related to

the consumer buying behavior. Factors as age and income may strongly influence

the buying behavior toward bottled water. For instance, it is assumed that young

people with middle and higher incomes are the best target group for bottled water

because of their potency and lifestyle.

To identify if psychological factors are directly related to the buying behavior of

bottled water; this research also considers psychological factors as one of the most

important type of factors which influences the buying behavior. The beliefs someone

has about something, determines his/her attitude toward and perception of it. One is

inclined to use something which he/she perceives to be good and is not inclined to

use something which he/she perceives not to be good.

To test these research questions in a field survey, hypotheses are developed for the

research questions/objectives. The next table shows a summary and list of these

hypotheses with the corresponding research question:

1.3 Justification for this research This research is justified on the following grounds:

1. Rapid growth of both global and local bottled water market and consumer adoption

rate; this justification is partly explained in section 1.1 (Research background). The

worldwide growth of the bottled water market creates numerous commercial

opportunities for bottlers, retailers and brand owners. Moreover, it is combined with

growing health awareness of the general public.

2. Gaps in research; this justification emphasizes the lack of research in this area.

Even though information regarding buying behavior may be helpful to bottled water

marketers, research about this issue in Surinamese context is sparse.

3. Anticipated benefits to provide guidance for bottled water marketing activities;

the results of this research may provide potential benefits to bottled water marketers,

bottlers or retailers. Marketing campaigns may be aimed more towards the (potential)


customer by having the right information about the consumer. For example, building

the product image of health, pureness or taste depends on findings of consumers’

perception and buying behavior of bottled water.

1.4 Limitation of scope The major limitation for this research is that it is confined to the city of Suriname,

Paramaribo. This geographical limitation is not only chosen because of time and access

restrictions, but also because of the fact that the major part of the Surinamese population is

concentrated in Paramaribo. The city is therefore considered as a good representation of the

whole population.

Furthermore this research is only researching the consumer buying behavior of bottled

water, since the consumption pattern from other products may differ. Consumers show an

unique buying behavior to every single product. For instance, the buying behavior toward

milk or alcoholic drinks differs from bottled water.

This research also limits itself to the Surinamese consumer, since it is considered that

consumers of different parts of the world behave differently because of cultural factors.

Although the bottled water market is global, generalization of the findings of this research

beyond Suriname is therefore not recommended.

Finally, only some demographic and psychological factors are selected for this research.

Although there are more types of factors which influence the consumer buying behavior, only

two types are investigated by this research. This as a result of time and administration

restrictions. Hence, not all possible results are explored by this study.

1.5 Significance of this research

The significance of this research expresses itself by being a helpful tool for marketers,

bottlers and retailers of bottled water to direct marketing campaigns in the right way.

Moreover, there is no

grounded research about the Surinamese bottled water market and the consumers buying

behavior toward the product.



1.6 Chapters content The content of this research consists of six chapters. Chapter 1 (Introduction) indicates the

research problem and introduces the subject area. This is followed by the literature review

(chapter 2), which analyses the existing literature about the subject field to develop a new

concept to be tested by this research. Thereafter Chapter 3 (Research Methodology)

describes the execution of this research to achieve the research objectives. Chapter 4

(Findings) describes the results of the research by giving facts. These results are analyzed

and tested on the research model in Chapter 5 (Analysis). Finally the author describes the

conclusions drawn from the findings and gives relevant recommendations on the basis of the

conclusions. This is presented in Chapter 6 (Conclusions & Recommendations).



CHAPTER 2 Literature review

2.1 Introduction

For a seemingly basic food product, the demand for bottled water has increased worldwide

and has generated an impressive market share. Due to the report Asia boosts global bottled

water market of Drake (2010), the bottled water market -again- had a likely increase of 4%

in 2009, compared to 2008. If this increasing trend continues, the global market is forecast to

have a value of $86,421.2 million in 2011, an increase of nearly 42% since 2006.7

This chapter analyses the existing literature on the bottled water market and consumer

buying behavior. Hence, on the basis of the existing literature, this chapter develops a

theoretical framework which will be tested by this research. First an introduction of this

chapter is given in section 2.1, before describing bottled water and its market generally in

section 2.2. Section 2.3 analyses the existing literature of key writers. This is followed by a

contribution of the researcher to the research field in section 2.4. Finally a summary of the

chapter is given in section 2.5.

2.2 Bottled water Water. A natural resource we can hardly live without. A great part of us has access to it

against minimal costs. But at the same time many people still do not have access to safe

drinking water because of limited or polluted resources.

Over the past decade there has been a remarkable increase in the bottled water market. It

can be stated that a phenomenon occurred within the water industry: bottled water.

There are several types of bottled water. Appendix A shows the main differences between

mineral, spring, well, distilled, purified, tap and other drink water.

2.2.1 Definitions

During the years ‘bottled water’ has been described in a number of different ways. For this

research the following definition is used on the basis of relative simplicity and clarity:

Bottled water is any product, including mineral, spring or well water taken from municipal or

private utility systems, distilled or other water, to which chemicals may be added and which

are put into sealed bottles, packages or other containers to be sold for domestic

consumption or culinary use. (Department of Health, New York State, 2006).

Furthermore the concept ‘global market’ was adopted as follows due to the relevant

information sources for this research:

The global market is divided into and refers to Asia, Europe, North America and All others.8

With regard to this research, these parts of the world all consist of their official countries.

2.2.2 Historical background The bottled water market started in Europe and Russia by the early 1900’s and extended

years later to the US and China. Throughout history, water was to survive. Starting with a

very small market, the main reason to use bottled water was health concerns (possible

medicinal properties).

It was in the early 19th century when the market showed a noticeable change in Europe and

captured a great part of the beverage market share. The real boost of bottled water

commenced in 1968 when the French company ‘Vittel’ revolutionarily launched the first

plastic bottled water- aimed for general public consumption. With France and Germany on

top with their highest sales in volume, Europe became an established and leading market.9

Bottlers marketed the product to consumers as safer, healthier, refreshing, more reliable and

above all, better than other soft drinks. Moreover, consumers had become more health

conscious and in some parts of the world tap water was unavailable or unsafe. These drivers

were the beginning of a booming global bottled water market.

2.2.3 Global bottled water market Thirty years ago, bottled water barely existed as a business. Nowadays we drink globally

millions of bottles a week. And this, while water is a product which can often be obtained for

minimal costs from taps in our homes. Moreover, we are grown up on tap water since many

of us have access to it. The next paragraphs briefly describe the growth and value of the

global market.

2.2.3.1 Market growth

After several leading years, the European and North American market deteriorated

somewhat over the last years. Drake (2010) argues in his report Asia boosts global bottled

water market that these markets showed a decrease in growth in 2008 and 2009 because of

two main reasons. Firstly because of the global recession (consumers are switching to less

expensive options such as tap water), and secondly because of concerns about the impact

of bottled water on the environment. It can be concluded that bottled water is an “extra”

commodity for many consumers in these countries since financial concerns play a crucial

role.

Thanks to the developing Asian market the global market maintains stable. It is China who

boosted the regional and indeed the global market. The rapidly growing economy of China

can be seen as the main driver of this growth. The global market increased by approximately

2% in 2009. This is a slowdown in comparison to previous years, but it also expresses that

the bottled water category can maintain growth in even the most challenging times of trading

environments.



2.2.3.2 Market value

The value of the global bottled water market increased obviously parallel to the consumption.

In 2012 the global bottled water market is forecast to have a value of $94.2 billion, an

increase of 41% since 2007. Despite the decline in growth last year, consultants expect

every region of the market to post growth in 2010.10

2.2.4 The Surinamese bottled water market The market of bottled water in Suriname has been growing consistently and has captured a

remarkable share in the beverage market for the last five years.11 From 2005 on, the market

-with mainly local bottlers and brands- has become an almost indispensable category to

consumers. Strong competitive prices, aggressive promotion to achieve brand awareness

and brand loyalty, and a good availability, are some of the aspects which set the basis for a

stable and strong competitive market. The market currently consists of the following bottled

water brands:

2.3 Literature of research area During the last decennia several institutes -such as Pacific Institute and the Australian

Bottled Water Institute (ABWI)- and writers have made their opinion about bottled water to

be known. Both proponents and opponents expressed themselves as the market turned into

a global phenomenon.

2.3.1 Bottled water There have been several studies over the past years to investigate what factors exactly have

been driving the buying behavior of consumers toward bottled water. The outcomes of these

studies and opinions of researchers vary widely.

Doria (2006) stated in his article Bottled water versus Tap water: understanding Consumers’

Preferences that several studies have shown two main drivers for bottled water

consumption. These drivers concern consumers buying behavior in USA, Canada and

France. The drivers are: organoleptics (water characteristics that affect the senses of taste,

odour and sight) and health and risk concerns (risk concerns may be seen as safety). Doria

(2006) argued that many consumers in these developed countries are not satisfied with the

tap water quality. Moreover, the consumption of bottled water have often been high in

communities that have serious problems with their tap water. Such problems provide new

opportunities for bottled water producers and marketers, who present their product as ‘pure’,

‘safe’ and ‘healthy’. He also argued that consumers are sensitive to the marketing of the

business. Not only the advertisement, but also the package influences their buying behavior.

As many consumers prefer products which seem to have higher health benefits, a great part

perceives bottled water to be reliable and, most of all, healthier than other water.

Rodwan (2009) partly agrees with Doria (2006). Rodwan (2009) agreed in his report

Confronting Challenges that the bottled water industry is just taking advantage of the

growing health and well-being consciousness of consumers. However, he stated another

main reason of consumers in developed countries as the USA and Canada. Consumers in

developed countries perceive bottled water as a good alternative to other beverages, such

as carbonated soft drinks and juices. It is not only a way to achieve hydration for them, but it

is also healthy and thirst-quenching.

It is in the developing countries, Rodwan (2009) argues in contrast with Doria (2006), where

bottled water serves as an alternative since these countries often have unsafe water. 16



In contrast with both Doria (2006) and Rodwan (2009), Shandling (2008) did not come to a

regional conclusion in her report Global bottled water consumption on the rise. She claimed

another main global driver: an increased awareness of people of the need for and benefits of

hydration for body and mind. Furthermore, bottled water is becoming more accessible in

growing economies such as Latin America and Eastern Europe, she argued. The results of

this research will also show to what extent this theory is applicable to the Surinamese

market.

Phend (2009) took the study of driving factors in bottled water consumption further. She

admits that earlier studies indicated the perceived purity, safety and taste as the main drivers

for consumers to use bottled water. However, on the basis of a more recent survey

conducted in England, she argued that health is not a driving factor in bottled water

consumption. It is convenience and taste which drive the use of bottled water. Due to Phend

(2009), the municipal water systems are improving the last years and prices of bottled water

are very high in comparison to tap water.

Overall, the reasons for bottled water consumption seem to vary; both by author and

country. Health/risk concerns and taste seem to be the most frequently mentioned causes.

The main conclusion is that consumers generally value bottled water and are prepared to

pay several times more to consume what they perceive to be a “safe”, “healthy”, “tasty” or

“convenient” product.

2.3.2 Consumer Buying Behavior Understanding consumer behavior and “knowing customers” is not simple. Customers may

say one thing but do another. They can get influenced and change their mind the last

minute. Or their needs or wants change from time to time. Consumer buying behavior refers

to the buying behavior of final consumers- individuals and households who buy goods and

services for personal consumption.12

2.3.2.1 Consumer decision process

According to Kotler et al. (2008), consumers pass through several stages before purchasing

something. They argue that the buying process is one which starts long before the actual

purchase and continues long after. The marketer therefore needs to focus on the entire

buying process, rather than just the purchase decision. Figure 2.2 shows the consumer

decision process with influencing factors.

England: Pearson Education Limited.

The process starts when the buyer recognizes a problem or need. Thereafter the buyer will

or will not search for more information related to the need. This information will be used to

evaluate alternative brands in the choice set. After evaluation, the buyer actually buys the

product. Based on the satisfaction or dissatisfaction of the buyer, he/she will take further

actions after the purchase.


Kotler et al. (2008) agree that the next factors strongly influence the buying behavior of

consumers: cultural, social, personal and psychological factors. The consumer’s choice

therefore results from the complex interplay of all these factors. Although the marketer

cannot influence many of these factors, they can be useful in identifying potential customers

to serve their needs better.

2.4 Contribution to research area

The discussion about the quality and other aspects (such as health benefits) of tap and

bottled water is still going on. Till today the opinions about bottled water differ and

researches show different results. Nevertheless, in most cases consumers do choose for

bottled water for one or more of the following reasons:

o Health/risk concerns

Consumers have become more health-conscious during last decade and bottled water has

the attraction of no calories and no additives. Besides, it is being presented as purer,

healthier and more reliable than tap water.

o Quality

In many countries the public water supply is unsafe or of inferior quality. As a result, many

people do prefer bottled water.

o Marketing

From promotion to packaging; effective marketing has increased the demand for bottled

water. As a real business, bottled water brands are sharply competing against each other by,

amongst others, competitive prices and aggressive promotion.

o Convenience

For many people, bottled water is just a convenient beverage, especially when they are on

the go. It is easy to carry and almost everywhere available.

It can be concluded that part of these driving factors are strongly psychologically determined.

Since there are no explicit results yet about the nature of bottled and tap water, it seems to

be in the mind of people that bottled water is better than tap water. 19



As seen in the previous section, psychological factors is one group of factors which generally

influence the consumer buying behavior.

This research focuses on two psychological factors which influence consumers: beliefs and

perception. Furthermore, this research looks into the possible relationships between

demographic factors (personal factors) and consumers’ buying behavior of bottled water.

Due to Kotler et al. (2008), a belief is a descriptive thought that someone holds about

something. These, in turn, influence the buying behavior. Perception is the process by which

people select, organize and interpret information to form a meaningful picture of the world.

The concept of this research argues that there may be a relationship between these factors

and the consumers buying behavior of bottled water.

2.5 Summary

Bottled water has become a phenomenon over the last decade. The increasing trend in the

consumption and market value explains that consumers are willing to pay a premium for it.

And this, while it is a product which they can get –in most cases- at minimal costs. Moreover,

the quality of bottled water is still being disputed by researchers. This indicates that

consumers’ beliefs and perception probably play an essential role in their buying behavior

toward bottled water. These psychological factors are one of the four groups of factors which

influence consumers’ buying behavior: cultural, social, personal and psychological factors.

The personal and psychological factors are subjects of this research. This research

investigates to what extent consumers’ beliefs and perception do influence their buying

behavior of bottled water. The relationship between the demographic factors of consumers

and their buying behavior of bottled water is also being investigated.



CHAPTER 3 Research Methodology

3.1 Introduction This chapter details the methodology which is used for this research to collect the data

needed. There are several steps to follow in order to gather the right data. Before explaining

these steps, the next section will firstly explain why this methodology is chosen. The next

figure shows an outline of this chapter with section numbers and inter-relationships.

Figure 3.1 Outline of Chapter 3 with section numbers and inter-relationships


The chapter begins with an outline of the methodology (Section 3.1) and an explanation for

selecting this research design (Section 3.2). The justification is followed by procedures of

how the survey is planned, conducted and administered, including the questionnaire design

and administration (Section 3.3) and the sampling strategy (Section 3.4). The data analysis

strategy will then be explained (Section 3.5), followed by a summary (Section 3.6) of all

sections.


3.2 Justification of survey methodology This background section first describes the strategy used for this research and then the

design to gather data.

3.2.1 Research strategy The strategy for this research can be classified as positivism because of some main

reasons.13 First, it deals with reality which is governed by natural laws. This research is

focused on the factors which influence consumers buying behavior. This can literally be

described as reality, influenced by laws derived from nature- apart from laws established by

human authorities. Second, the reality is explored by empirical research and a survey study.

These types of research enable it to collect a relatively high amount of reliable data against

relatively low costs. Third, the research consists of hypotheses that can be regarded as

facts. As seen in chapter one, this research consists of several hypotheses to be tested by a

survey study (quantitative data), to discover relationships among variables. Finally, the

researcher is objective and independent from the subject.

Furthermore, this research is being approached in a deductive way. The main characteristic

of a deductive approach is that the researcher develops a theory and one or more

hypothesis/ hypotheses. The researcher starts from the hypothesis/hypotheses that is/are

developed on the basis of general principles.14 These hypotheses are expressed in

operational terms to test them by the collection of quantitative data.

3.2.2 Research design A research design is a plan which outlines how information is to be gathered for an

assessment. It includes identifying the data gathering method(s), the instruments to be

used/created, how the instruments will be administered, and how the information will be

organized and analyzed.15

This research uses a mixed approach of two research strategies; exploratory and descriptive

research. Each of these strategies plays a distinct but complementary role in order to get an

answer on the research problem. Exploratory research is conducted into an issue or problem

where there are few or no earlier studies to refer to. The focus is on gaining insights and

familiarity for later investigation. Descriptive research describes phenomena as they exist.

Here, data is often quantitative and statistics are applied. It is used to identify and obtain

information on a particular problem or issue. 16

Firstly, exploratory research is carried out to gain insights and background information about

the phenomenon of bottled water, both globally and locally. By doing this, little academic

research and literature is discovered. This helped to identify various variables of consumers’

perception and buying behavior.

Thereafter, descriptive research is used to test and to answer the research hypotheses. This

is carried out by a survey design and therefore consists of designing and administrating the

questionnaire, constructing the sampling strategy and analyzing the results.

The survey design is being considered as the most appropriate technique for descriptive

research since the aim is to obtain primary data. Questionnaires (primary data) enable the

researcher more easily to identify and describe the opinion of the respondents. Moreover, it

is simple to administrate, provides relatively reliable data and is time limited. Because of the

fact that every respondent is asked to answer the same set of structured and predetermined

questions, coding, data treatment and interpretation is relatively easy.

3.3 Questionnaire design and administration Firstly, all questions and formats are standardized so that all respondents face the same

questionnaire. Second, the questionnaire is designed comprehensively, in order to motivate

respondents to cooperate and accurately complete it.


15 Wikipedia (2007). Instructional Assessment Resources (IAR): Glossary. Retrieved from http://www.utexas.edu/academic/diia/assessment/iar/glossary.php 16 WikiAnswers (2010). What is exploratory research? Retrieved from http://wiki.answers.com/ Q/What_is_exploratory_research

http://www.utexas.edu/academic/diia/assessment/iar/glossary.phphttp://wiki.answers.com/


The questionnaire used for this research is included in appendix B. Malhotra (1999) provides

a set of seven steps of questionnaire design which is used for this research.

3.3.1 Step 1: specifying the data required The first step in questionnaire design is to accurately determine the required information to

achieve the research objectives. Based on the research questions, hypotheses and the

exploratory research, the independent and dependent variables are identified as shown in

table 2.1.

2. How do psychological

buying behavior?

Table 2.1 Research questions with independent and dependent variables


In order to test the hypotheses, the questionnaire used for this research is divided into two

parts: one to measure the correlation between demographic factors and buying behavior

(Q1-Q4), and one to measure the correlation between psychological factors and buying

behavior (Q5-Q25).

Q1 till Q4 is a set of close-ended questions. Q5 till Q25 partly exist of statements with a four

point scale from ‘strongly agree’ to ‘strongly disagree’ and partly of questions with three or

four options to choose from. This is purposely developed to determine the relationship

between buying behavior and psychological factors.



3.3.2 Step 2: specifying the survey method

The next step of the questionnaire design is to specify the survey method. The survey

method is the research technique which gathers information from people through the use of

surveys or questionnaires.17 Primary data can be collected in a number of ways. However,

every type of survey method has its advantages and disadvantages.

The choice of the most appropriate method depends on both the research objectives and

constraints. Factors such as required accuracy level, time and costs are considered, as well

as the advantages and disadvantages of the survey methods as summarized in table 2.2.

Hence, the choice of a self-administered survey for this research is based on the research

objectives and an assessment of the advantages and disadvantages of survey methods.


.

A self-administered survey is a survey in which respondents answer questions directly on a

questionnaire without an interviewer’s interaction.18 The respondent completes the survey

on his or her own and can choose his or her own pace and time to complete the survey

This type of method is considered as the most appropriate method for this research because

of several reasons. It can not only be cost-efficient, but it can also improve the reliability of

the results since respondents are not rushed to fill it out. However, the possible

disadvantages of a self-administered survey are also taken into consideration carefully. For

example, it is important that the respondents understand the questions right and answer it in

an understandable way. Therefore the questions are formulated as clear as possible for

everyone. There is also a chance that respondents will not complete the questionnaire or will

not respond in a timely manner. These factors are taken into consideration as ‘errors’ (see

section 3.4).

3.3.3 Step 3: developing measurement scales

Closely related to the design of the questionnaire is selecting the format of response for

measurement. There are four types of scales: nominal, ordinal, ratio and interval.

The three types of measurement scales in the questionnaire of this research are nominal,

ordinal and interval. For example question one (Gender) has a nominal scale, since there is

17 McGraw-Hill (2004). Glencoe Marketing Essentials. Retrieved from www.glencoe.com 18 McGraw-Hill. (2004). Glencoe Marketing Essentials. Retrieved from www.glencoe.com

http://www.glencoe.com/http://www.glencoe.com/


no magnitude, no equal interval and no absolute zero in the possible answers. Question

three (Education) is ordinal because of possible ranking but no magnitude and absolute zero

point. The questions five till twenty can be treated as questions with interval scales, as it is

communicated and produced in an interval-scaled way.

3.3.4 Step 4: reliability and validity test Any questionnaire should be reliable and valid in order to use the right results for further

actions. Reliability is the consistency of your measurement. It is the degree to which an

instrument measures the same way each time it is used under the same condition with the

same subjects. In short, it is the repeatability of your measurement. A measure is considered

to be reliable if a person's score on the same test given twice is similar.19

In order to test the reliability of this questionnaire, a pilot test is carried out prior to the field

survey within a relatively small sample of 10 respondents to identify and eliminate possible

problems.

Validity is concerned with the strength of our conclusions, inferences or propositions. More

formally, Cook and Campbell (1979) define it as the "best available approximation to the

truth or falsity of a given inference, proposition or conclusion." In short, were we right? How

well did we measure what we claim to measure by a specific research method? 20

Regarding this research, the validity is verified by the supervisor of this research, who looks

into the appropriateness of questions and the scales of measurement.

3.3.5 Step 5: preparing draft questionnaire


To design a good questionnaire, principles are applied to the content, wording and structure

of the questions. Double-barreled and sensitive questions are avoided. As well for wording,

care is taken to ensure that words have only one meaning and there are no biased words,

phrases, abbreviations, double negatives and incomplete sentences. In relation to the

structure, all questions have a clear structure and the questionnaire is divided into three

http://www.socialresearchmethods.net/tutorial/Colosi/lcolosi2.htmhttp://www.socialresearchmethods.net/tutorial/Colosi/lcolosi2.htm


parts. They are ordered from the most easy ones (personal information) to the more time-

consuming and topic-related ones. Furthermore, questions with similar structure are grouped

together.

3.3.6 Step 6: testing, revising and distributing the questionnaire

As mentioned in section 3.3.4, the validity and reliability of the questionnaire are assessed in

the testing phase. Revision takes place on the basis of the feedback from the respondents.

The distribution of the questionnaires takes place through the network of the researcher and

a team of two persons. This team is located at several locations within the centre of

Paramaribo to distribute and collect the questionnaires. This team is also responsible,

together with the researcher, to ensure that all questionnaires are completely answered and

valid for data analysis.

3.3.7 Step 7: questionnaire administration As required, this questionnaire is designed to encourage responses as much as possible.

Hence, it is designed to appear quick and easy to answer, mostly by the close-ended

questions. The average time required to complete the questionnaire is confined to be 5- 8

minutes. Furthermore, a pen is provided to every respondent who completes a questionnaire

to stimulate the response rate. Finally, some aspects are taken into consideration and given

out with every questionnaire to establish trust and make the respondent feel comfortable.

These aspects are: an introduction with the identity of the researcher, the nature and

importance of the research and principles to ensure anonymity.

3.4 Sampling strategy

Another crucial step in conducting the survey is to determine which subjects shall be

surveyed to obtain the appropriate information for the research objectives. To decide which

type of sampling will be the most appropriate one for this survey, the characteristics of both

probability and non-probability sampling are considered.

Probability sampling is one in which every unit in the population has a chance (greater than

zero) of being selected in the sample. At Non-probability sampling some elements of the 27



population have no chance of selection, or the probability of selection cannot be accurately

determined. It involves the selection of elements based on assumptions regarding the

population of interest which forms the criteria for selection.21

The sampling process of this research comprises several stages:22

Defining the population of concern;

Specifying a sampling frame, a set of items or events possible to measure;

Specifying a sampling method for selecting items or events from the frame;

Determining the sample size;

Implementing the sampling plan;

Sampling and data collection;

Reviewing the sampling process

In this research, the population of concern consists of all Surinamese people who live in the

capital Paramaribo, have at least a foundation education and are sixteen years or older.

The sampling frame is in this case the same as the population of concern. The sample frame

is a set of items from which the sample is drawn. Since it is hardly impossible to list all the

people with above mentioned characteristics, the sample frame is the same as the

population of concern.

The most appropriate sampling method for this research is quota sampling, a form of non-

probability sampling. In quota sampling the population is first segmented into mutually

exclusive sub-groups. Then judgment is used to select the subjects or units from each

segment based on a specified proportion. This type of sampling is considered as the most

appropriate one for this research because of two main reasons. Firstly, it enables the

researcher to list relevant control characteristics and secondly it determines the distribution

of these characteristics in the targeted population. Demographic data, such as age and sex,

can more easily be explored by quota sampling.

Determining the sample size for probability samples involves financial, statistical and

objective considerations. Due to the limited time for this research, the sample size of this

study is 200. In addition, a sample size of 20 is taken into consideration for errors.


21 Wikipedia.(2010, February). Sampling (Statistics). Retrieved from http://en.wikipedia.org/wiki/Sampling_(statistics) 22 Wikipedia.(2010, February). Sampling (Statistics). Retrieved from http://en.wikipedia.org/wiki/Sampling_(statistics)

http://en.wikipedia.org/wiki/Sampling_(statistics)http://en.wikipedia.org/wiki/Sampling_(statistics)


Thereafter the implementation of the sampling plan takes place after all necessary

preparations. During two full weeks questionnaires are distributed via several locations

within Paramaribo. Sampling and data collection are carried out directly after the distribution,

since the questionnaires are collected within two days maximum.

Finally the sampling process is reviewed in order to guarantee reliability, validity and

readiness for analysis.

3.5 Data analysis strategy The data collected from the questionnaires is completely summarized and analyzed by using

Statistical Package for Social Science (SPSS) version 17.0. SPSS enables accuracy and

makes it relatively easy to interpret data. The following analysis statistics were undertaken in

SPSS for further analysis:

Descriptive:

1. Frequencies;

2. Descriptives

Associative:

1. Reliability;

2. T- test;

3. One way Analysis of Variance (ANOVA);

4. Correlations

Firstly, frequencies and descriptive statistics summarize some main data of respondents to

get an overview and to provide guidance for conducting further analysis. Secondly, t-test,

ANOVA and correlations amongst dependent and independent variables are carried out to

identify the possible relationships.

3.6 Summary The choice of approach for this research is made on the basis of the nature of the research

and the advantages and disadvantages of all possibilities. The positivism-deductive



approach is considered to be the most appropriate method for this research. This approach

enables the researcher to gather the data needed in a relatively simple, cost-efficient and yet

structured and reliable way. This, by exploratory and descriptive research. The approach

consists of three main stages: questionnaire design & administration, sampling strategy and

the data analysis. This last stage takes place by using Statistical Package for Social Science

(SPSS); a program to easily interpret data.



CHAPTER 4 Findings

4.1 Introduction This chapter illustrates the results of the data collected. Section 4.1 is the introduction to the

chapter, while section 4.2 describes how the data is prepared for analysis. Section 4.3

illustrates a general profile of the collected data, where after section 4.4 and 4.5 outlines this

data profile by respectively descriptive and inferential statistical results. These results are

obtained after transfer and edit of the data in SPSS. Section 4.6 summarizes this chapter.

4.2 Data preparation In order to make all the collected data suitable for the analysis, all questionnaires are

screened to be complete. All returned incomplete questionnaires are therefore considered as

errors and removed from the survey data. Out of the 220 distributed questionnaires, 18 are

incomplete. As mentioned in section 3.4, 20 questionnaires are taken into consideration as

errors. Hence, in total 200 of the 202 complete questionnaires are being used for this

research.

Each question and possible answer of the questionnaire has a code, since coding of data is

necessary for transferring and editing data in SPSS. The questions and possible answers

are corresponded in the order of the actual questionnaire.

The answer possibilities are recoded before the analysis. This, to make it possible that a

higher score of the respondents corresponds with a higher correlation between the variables.

Since the questions of the actual questionnaire are coded negatively (a high score

corresponds with a low correlation), the questions are recoded for the ease of analysis.

Question 12 and 13 also concern the buying behavior of bottled water, but with nominal

scales. Therefore the results of these questions (main purchase location of and main reason

to buy bottled water) can be seen in table 4.1.

Question 14 of the questionnaire deals with factors which possibly influence the buying

behavior of consumers. Table 4.5 shows the results.

Table 4.5: Statistics of the extent to which factors influence bottled water buying behavior


The next standard is assumed regarding the means of table 4.5:



1.00 – 1.49 Low influence

1.50 – 2.49 Moderate influence

2.50 – 3.00 High influence

Appendix C shows the reliability of the variables of table 4.2, 4.3 & 4.5. Furthermore,

appendix D shows the statistics from both the dependent variable (buying behavior) and the

independent variables (beliefs & perception).

4.5 Inferential statistics This section tests the relationships between the different dependent and independent

variable(s) in order to get an answer to the research questions. The hypotheses of the

research (section 1.2) form the basis. In order to know to what extent there is a relationship

between the different variables, the correlation coefficient is examined. This coefficient is a

measure which indicates the strength and direction of a linear relationship between two

random variables. It can vary from -1 (perfect negative correlation) through 0 (no correlation)

to +1 (perfect positive correlation) and is also known as the Pearson Correlation Coefficient

(r-value).23 In other words, if the correlation coefficient value is close to either -1.0 or 1.0, it

means that there is a strong negative or a strong positive relationship between the two

variables. Generally the strengths of the correlations are determined on the basis of the

following standard:

Correlation range Size of correlation

.10 - .29 Small

.30 - .49 Medium

.50 – 1.0 Large

The Sig. (1-tailed/ 2-tailed) value expresses a value to accept or reject the (nul) hypotheses.

It is also called the p-value. The p-value is the probability that the correlation is one just by

chance. Therefore the smaller the p-value, the better. Generally the rule is: reject H0 if p ≤

.05 and accept H0 if p ≥ .05. 24

Since the variable ‘gender’ consists of only two groups, the t-test is carried out at this

variable. At the variables ‘age’, ‘education’ and ‘income’ the ANOVA is carried out, since

there are more than two groups to analyze there. The descriptive of these 3 variables are

shown in appendix E. The variables ‘beliefs’ and ‘perception’ are carried out through

correlations to identify the relationships. These results, and therefore the results of the

hypotheses, can be found in (the tables of) appendix F.

The t-test shows that there is no relationship between ‘gender’ and ‘bottled water buying

behavior’ (table F1). The p-value (Sig. 2-tailed) of .688 indicates this. Therefore H0 1.1 is

accepted.

Table F2 concerns the relationship between ‘age’ and ‘bottled water buying behavior’. The p-

value (Sig.) of .402 of the ANOVA indicates that there is no relationship between these 2

variables. H0 1.2 is accepted.

Thereafter the relationship between ‘education’ and ‘bottled water buying behavior’ is tested

(table F3). The p-value here is .241 and therefore H0 1.3 is accepted. There is no

relationship between ‘education’ and ‘buying behavior’.

The relationship between ‘income’ and ‘bottled water buying behavior’ is tested in table F4.

The p-value here is .009, which indicates that there is a relationship between these

variables. H0 1.4 is rejected.

Finally both variables ‘beliefs’ and ‘perception’ are tested on a relationship with ‘bottled water

buying behavior’ (table F5). The p-value of ‘beliefs’ is .498 and of ‘perception’ is .011.

Therefore there is no relationship between ‘beliefs’ and ‘bottled water buying behavior’, but

there is a relationship between ‘perception’ and ‘bottled water buying behavior’.

H0 2.1 is accepted and H0 2.2 is rejected. Based on the correlation size (see table 4.6), the

relationship between ‘perception’ and the ‘bottled water buying behavior’ can be described

as small.

4.6 Summary

This chapter begins with a profile (expressed in numbers and percentages) of the collected

data to gain some insights. The profile shows the demographic factors and the bottled water

buying behavior of the sample size. The distribution of the sample size is also shown by the

profile, as it must adequately represent all parts of the sample. By showing the descriptive

results, insi
