What is Research?

What is RESEARCH?

• Nachmias and Nachmias (1981, p. 22): “the overall scheme of scientific in which scientists engage in order to produce knowledge”

• Kerlinger (1973, p. 11): “systematic, controlled, empirical, and critical investigation of hypothetical propositions about the presumed relationships among natural phenomena”

• Best (1977, p. 10-12): “formal, systematic, and intensive process of carrying out a scientific method of analysis which may lead to the development of generalizations, principles or theories which can result in the predictions and control of events”

What is RESEARCH?

Research is a systematic andorganised effort to

investigatespecific problem that needs

a solution

ATTRIBUTES OF RESEARCH

• Based on other works• Replicable• Generalisable• Tied of theory• Doable• Generates to New Questions• Incremental• Apolitical/Neutral

Type of Research

•Applied vs. Basic or

Fundamental Research

•Scientific vs. Naturalistic

Research

Basic Research

• Attempts to expand the limits of knowledge.• Not directly involved in the solution to a

pragmatic problem.

Basic Research Example

• Is executive success correlated with high need for achievement?

• Are members of highly cohesive work groups more satisfied than members of less cohesive work groups?

• Do consumers experience cognitive dissonance in low-involvement situations?

Applied Research

• Conducted when a decision must be made about a specific real-life problem

Applied Research Examples

• Determinants of Zakat Compliance Behaviour

• The effectiveness of Teaching Science and Mathematics Subjects in English.

• Attitude Towards PTK

• The effect of Tax Rates on Company Capital Invesment

Type of Research

•Historical Research vs. Methodological Research

•Qualitative vs. Quantitative

"The secret of success is to know something nobody else knows. "

Aristotle Onassis

How to do Research?

Motivation

The Significance of the study

The ‘why’ factor

Element of Motivation

• Have not been investigated before• Contribution to the body of

knowledge• Problem solving• Interest to you, academia &

profession• Lead to another question!• Are available to investigate

Methodological motivations vs “content” motivations

Methodological motivations:Concerns with methodology(e.g. type of data, statistical

model, sampling method, etc.)“Content” motivations:

Concerns with “content” (e.g. theory, new issues,

new variables)

Motivation for ‘applied’ and Academic Research

• Immediate application vs long term applicability

Developing a Researchable Issue

• Ideas/Issues•Research

Questions•Hypotheses•Models

Ideas/Issues

• Abstract - beliefs, conceptions,

suppositions, assumptions, what ifs, guesses, etc.

How to do Research?

The Research Process

RESEARCH PROCESS

Generally, research comprise the process of developing the

conceptual framework and the hypotheses for testing as well as the design, which involves the planning of the actual study

dealing with such aspects as the location for the study, sample

selection & data collection processes and results of the study.

Degree of Problem Definition

Exploratory Research

• Initial research conducted to clarify and define the nature of a problem

• Does not provide conclusive evidence

• Subsequent research expected

Descriptive Research

• Describes characteristics of a population or phenomenon

• Some understanding of the nature of the problem

I keep six honest serving men, (they taught me all I knew), their names are

--Rudyard Kipling

what, and why, and when,

and how,and where and

who.”

Descriptive Research Example

• Weight Watchers average customer

• Woman about 40 years old

• Household income of about $50,000

• At least some college education

• Trying to juggle children and a job

Descriptive Research Example

• Men’s fragrance market

• 1/3 size of women’s fragrance market

• But growing at a faster pace

• Women buy 80 % of men’s fragrances

Causal Research

• Conducted to identify cause and effect relationships

Identifying Causality

• A causal relationship is impossible to prove.

• Evidence of causality:– 1. The appropriate causal order of events– 2. Concomitant variation--two

phenomena vary together– 3. An absence of alternative plausible

explanations

Let’s Come Back to Problem Discovery and Definition

• First step• Problem, opportunity, or

monitor operations• Discovery before definition

“The formulation of the problem is often more essential than its

solution”

Albert Einstein

Desired State

Why?Factors?

Theory ConceptualFramework

Problem Definition

• The indication of a specific decision area that will be clarified by answering some research questions.

Statement of Research Objectives

Analysis of the Situation

Symptom Detection

The Process ofProblem Definition

Ascertain the decision maker’s objectives

Understand background of the problem

Isolate/identify the problem, not the symptoms

Determine unit of analysis

Determine relevant variables

State research questions and objectives

Understand the Background of the Problem

• Exercising judgment

• Situation analysis - The informal gathering of background information to familiarize researchers or managers with the decision area.

Isolate and Identify the Problems, Not the Symptoms

• Symptoms can be confusing

Symptoms Can Be Confusing

Twenty-year-old neighborhood swimming association:

• Membership has been declining for years.

• New water park -residents prefer the expensive water park????

• Demographic changes: Children have grown up

Twenty-year-old neighborhood swimming association in a major city.

Membership has been declining for years. New water park with wave pool and water slides moved into town a few years ago.

Neighborhood residents prefer the expensive water park and have negative image of swimming pool.

Demographic changes: Children in this 20-year-old neighborhood have grown up. Older residents no longer swim anywhere.

Determine the Unit of Analysis

• Individuals, households, organizations, etc.

• In many studies, the family rather than the individual is the appropriate unit of analysis.

Determine the Relevant Variable

• Anything that may assume different numerical values

Types of Variables

• Categorical

• Continuous

• Dependent

• Independent

• Moderating

• Intervening

State the research questions and research objectives

If you do not know where you are going,any road will take you there.

Hypothesis

• An unproven proposition

• A possible solution to a problem

• Guess
