INTRODUCTION

Healthy diet is one that helps maintain or improve general health. It is important for lowering

many chronic health risks, such as obesity, heart disease, diabetes, hypertension and

cancer.[1] A healthy diet involves consuming appropriate amounts of all essential nutrientsand an adequate amount of water. Nutrients can be obtained from many different foods, so

there are numerous diets that may be considered healthy.

A healthy diet needs to have a balance of macronutrients (fats, proteins, and

carbohydrates), calories to support energy needs, and micronutrients to meet the needs for

human nutrition without inducing toxicity or excessive weight gain from consuming excessive

amounts.

The World Health Organization (WHO) makes the following 5 recommendations with

respect to both populations and individuals:[2] Try to burn as much energy as you eat, and try

to eat as much energy as you burn, as a healthyweight is a balance between those two.

Increase consumption of food producing plants, particularly fruits, vegetables, legumes,

whole grains and nuts.

Then, limit intake of fat and oil, and avoid saturated fats, which are those that become

solid at roomtemperature such as coconut oil and all animal products including basically

meat, dairy and egg.Prefer unsaturated fats, which remain liquid at room temperature instead,

and which are found inalmost all the plant based oils and foods. Eliminate trans-fatty acids

and limit the intake of granulated sugar. Lastly, limit salt/sodium consumption from all

sources and ensure that salt is iodized.

PART I

If you look around your class, you will notice that your classmates are different in terms ofheight, mass, shoe size etc. You probably would have expected most people to be around the

average mass. Based on these studies, the ministry has collected data and interpreted it into

statistical data for further action.

Hence, briefly discuss

(i) history about statistic

Answer :

Statistics is the study of the collection, organization, analysis, and interpretation ofdata.[1][2]

It deals with all aspects of this, including the planning of data collection in terms of the design

ofsurveysandexperiments.[1]

The word statistics, when referring to the scientific discipline, is singular, as in "Statistics is

an art."[3]

This should not be confused with the word statistic, referring to a quantity (such as

meanormedian) calculated from a set of data,[4]

whose plural is statistics ("this statistic

seems wrong" or "these statistics are misleading").

The earliest writing on statistics was found in a 9th century book entitled: "Manuscript on

Deciphering Cryptographic Messages", written byAl-Kindi(801873 CE). In his book, Al-

Kindi gave a detailed description of how to use statistics andfrequency analysisto decipher

encrypted messages, this was the birth of both statistics and cryptanalysis, according to

Ibrahim Al-Kadi.[10][11]

Some scholars pinpoint the origin of statistics to 1663, with the publication ofNatural and

Political Observations upon the Bills of Mortality byJohn Graunt.[12]

Early applications of

statistical thinking revolved around the needs of states to base policy on demographic and

economic data, hence itsstat- etymology. The scope of the discipline of statistics broadened

in the early 19th century to include the collection and analysis of data in general. Today,

statistics is widely employed in government, business, and the natural and social sciences.

Its mathematical foundations were laid in the 17th century with the development of

probability theorybyBlaise PascalandPierre de Fermat. Probability theory arose from the

study of games of chance. Themethod of least squareswas first described byCarl Friedrich

Gaussaround 1794. The use of moderncomputershas expedited large-scale statisticalcomputation, and has also made possible new methods that are impractical to perform

manually.

(ii) application of statistic in everyday life.

Answer :

One of the application of statistic in everyday life is in quality testing. Statistics can form a

key basis tool in business and manufacturing as well. It is used to understand measurementsystems variability, control processes or summarizing data, and to make data-driven

decisions. In these roles, it is a key tool, and perhaps the only reliable tool.

For example, companies make thousands of products every day and each company must make surethat a good quality item is sold. But a company can't test each and every item that they ship to you,

the consumer. So the company uses statistics to test just a few, called a sample, of what they make.

If the sample passes quality tests, then the company assumes that all the items made in the group,

called a batch, are good item to be sold to the cunsumer.

PART II

The Ministry of Health has done many studies on the effect of food sold in the school canteen

on children.

To support the government effort, you are required to run the project. This project required

you to obtain the mass and height of 100 students in certain forms of your school.

Based on the raw data collected, tabulate your data into a frequency table as below:

f) Calculate the mean, variance and standard deviations. Explain briefly why mean, varianceand standard deviations are used in statistic to interpret data.

Answer :

Mean

Standard deviation

The reason why mean, variance and standard deviations are used in statistic to

interpret data because these are the types of measures of dispersion. Measures of dispersion

are the measures of the degree of dispersion in the statistic. It is important to determine how

far the values of data in a set of data scatter or spread out from its average value.

iii) An obese person is more prone to develop diseases such as diabetes, stroke and heart

attack.

Comment on this statement. Suggest ways and strategies that a person can adopt to reduce or

increase mass and live a healthier life.

Answer :

I totally agreed with the statement because an obese has a higher risk in getting many

dangerous disease like diabetes and heart attack. However, theres some ways and strategies

that a person can adopt to reduce or increase and live a healthier life.

First of all, fill up on colorful fruits and vegetables Fruits and vegetables are the

foundation of a healthy diet. They are low in calories and nutrient dense, which means they

are packed with vitamins, minerals, antioxidants, and fiber. Try to eat a rainbow of fruits and

vegetables every day and with every mealthe brighter the better. Colorful, deeply colored

fruits and vegetables contain higher concentrations of vitamins, minerals, and antioxidantsand different colors provide different benefits, so eat a variety.

Next is try to limit sugars and salts. Sugar causes energy ups and downs and can add to

health and weight problems. Large amounts of added sugar can be hidden in foods such as

bread, canned soups and vegetables, margarine, fast food, soy sauce, and ketchup. So, some

tips that we can practising it everyday is try to avoid sugary drinks. One 12-oz soda has about

10 teaspoons of sugar in it, more than the daily recommended limit! Try sparkling water with

lemon or a splash of fruit juice. We also recommended to eat naturally sweet food such as

fruits, peppers or natural peanut butter to satisfy our sweet tooth.

Lastly, we must exercise regularly in every week. Some warm up and strecthing can

release our stresss in a right way and also promotes bowel movement. Some basic exercise

that we can do everyday is weight-bearing exercie such as walking and weight training. This

exercise can prevent and also slow down bone loss and enchanting the blood flow in the blood

capillaries by giving the suitable pressure in the capillaries.

CONCLUSION

The conclusion is we can categoriesed a person in four categories. First categories is

underweight, then normal, overweight and lastly obese. The categories was differentiate from

the others by a fixed BMI range for each category. A person is called as underweight ifhis/her Body Mass Index,BMI is lower than 18.5. The normal person usually will have a BMI

from a range of 18.5 to 24.9. When a person have a higher BMI than that range, that person

will be called as overweight and if his/her BMI is 30 and higher it mean, that person in an

obese person. This type of person is very risky to get various type of dangerous deseases such

as diabetes and heart attack.

From the survey that have been done, we can conclude that the majority of the

students is in the normal category. However, theres still many students that didnt achievedan ideal BMI which is from18.5 to 24.9.Most of these students were in the underweight

category and only a few of them were in overweight and obese categories. This shows us that

nowadays, students doesnt like to eat and fear of getting fat. So, they willingly to starving for

the whole day just because they dont want to get fat as it will effect their personality towards

themselves.

A healthy person or in the other word the normal person is someone that doesnt doing

something in extreme. People often think of healthy eating as an all or nothing proposition,

but a key foundation for any healthy diet is moderation. Despite what certain fact diets wouldhave you believe, we all need a balance of carbohydrates, protein, fat, fiber, vitamins, and

minerals to sustain a healthy body. So,we should eats moderately and always follow the daily

requirement of the human body. This requirement was affected by some factors such as the

ages, body size, gender, genetic disposition of genes, occupations, lifestyle and lastly the

climate. As conclusion, we must eats according to this factors to fulfil our daily energy

requiremen so we could get an ideal physical state and a healthy body.

REFLECTION

While Im conducting this project, theres many new things that Ive learnt from my

family, teacher, friends and also from the information in internet. One of the things that Ive

learnt is now I know how to create many types of graphs by using Microsoft Excel 2007 suchdrawing of histogram and ogive graph. Before this, I never know how use Microsoft Excel

and I dont even want to learn about it but this project had forced me to learn about it in order

to complete this project. At least, Ive learnt something new.

While doing this project, theres plentiful of moral values that I did practice. One of it

is patience is the cure of anger. Theres always a mistake when drawing a graph using

Microsoft Excel as Im new with Excel and not use with it. This sometimes wasting my time

without gaining any result. However, its what we called as life and it taught me to be strong

and never give up in completing this project work.

After completing this project, first of all; Im so grateful to Allah as because of His

willingness I could complete this project. Secondly, I would like to thank to all those whose

helping me escpecially to my parents and my brotherssisters. Im also not forgotten to say

thank you to my lovely Addmath teacher,Pn. Ruhil and to all my friends who helped me

whether directly or indirectly by giving some useful information about this project.
