How are you going to gather data?

We will be surveying at least 30 students between the ages of 13 - 16 with the help of Google forms. The link of the form is: The respondents are students who live in Singapore. They are mostly friends and family members whom we have contacted via Facebook as they are easily accessible. The survey is spanned over a period of 2 weeks.

How are you going to collate data?

We will be using google forms as it is easy to use and and is able to collate data into spreadsheets conveniently. The survey would be mostly short answered questions so it is easier to look through and summarise the data. 

How are you going to shift and sort data i.e. which data is important?
The data will be sorted nicely in a spreadsheet by google forms. We will standardise and
edit some answers to it will be easier to look at as some answers may vary (e.g. Height      162cm/1.62m). The answers will be calculated to find the BMI. It will be collated to find the mean of the  results. Most of the data is all we need and all data is important.

Data Analysis:

How are you going to analyse the data?
We will find the average amount of time spent to exercise and then compare it with the average BMI and see whether it is a major factor affecting BMI. We will also see if the students are aware that exercising affects their BMI.

How are you going to present the data?

The statistics on the amount of time spent exercising for a person who is in the low, healthy and high range of the BMI will be shown through a graph. The statistics on whether the students know that exercise affects their  BMI and how much they exercise will also be shown on a graph. This measures will allow us to see the trend and find the root cause of the problem. We can also present the data from different perspectives using different  graphs (e.g. Pie Chart) to allow us to have a better understanding of the trend.

scene 1: showing the problem

xavier and junkai gets their height and weight and BMI from their their teacher(issac).

We will then show part of both of the students daily life
Xavier: active and healthy
Junkai: lazy and unactive

Then they will then go for health education class showing how BMI affects the body

Junkai( overweight boy)
Xavier( healthy boy)
Issac( PE teacher)
Roger( health education teacher)

Scene 1:

Issac: xavier and Junkai, please come over here.
*walks towards issac*
Issac: Xavier your BMi is 20, very good you are in the healthy range. Junkai, your BMI is 30, That is very bad, you are borderline severely overweight, you have to exercise more.

Scene 2:
*Xavier eats an apple*
Xavier: an apple a day keeps the doctor away
Xavier then runs around the feild one time

Scene 3
* eats laksa *
Junkai: nothing better than a big bowl of laksa.
Junkai then proceeds to sleep

Scene 4
*roger walks into the class*
Junkai and xavier: good morning mr Ong
Roger: good morning, today i will teach you about BMI
* shows dangers of high BMI*

Amount of exercise done in regular intervals

Dependent variable:
Change in Body-Mass-Index

People that have the healthy range of BMI before experiment.
Age Group


  1. Why is your research important?
It allows people to know that lack of exercise might cause a change in the BMI. Having high or low BMI increases health risks.

  1. How does it contribute to existing body of knowledge?
It contributes about the relationship between exercising and the BMI. With the help of this research, people would understand that it is very important to exercise regularly and the effects of exercising to the BMI.

  1. How does your research contribute to/impact the society or community?
It impacts the society to think about exercise regularly because it may affect their BMI in the long run.


The "scope" section is where you list what you are doing. The "bounds" section is where you set the boundaries and you list some thing explicitly that you are not doing because they are outside the bounds of the project.

1. Effects of low and high BMI e.g. illnesses (Bound)
2. How frequent people exercise (Scope)
3. Have a control and the variable for the experiment (Scope)


  1. What are the current research available/ you have come across?
Relation of exercise capacity and body mass index to mortality in patients with intermediate to high risk of coronary artery disease.

  1. Summarise the research articles that you have encountered which may be useful to your research.
Both increased exercise capacity and BMI were associated with lower mortality in patients with an intermediate to high likelihood of CAD (coronary artery disease) after controlling for confounding variables, supporting an inverse impact of BMI on mortality.



  1. How are you going to gather data?
1)     Survey of 500 adults between the ages of 21-35 with the help of Google forms.

  1. How are you going to collate data?
2)     Google forms will put the available data into spreadsheets.

Research justification


Research Topic: Health
Chosen Area of Focus: Will the lack of exercise affect Body-Mass-Index?

 1. Framing our research topic
Our chosen area of focus is Many adults are unhealthy because of lack of exercise’’. We have chosen this topic as it shows us how one can exercise to ensure that we keep fit by exercising properly and how it affects our health. Exercise has long been touted as the panacea for everything that ails you. For better health, simply walk for 20 or 30 minutes a day(Gina Kolata, 2008)

a)Possible reasons for many adults being unhealthy because of lack of exercise. “A research conducted about exercise says that exercising helps reduce Cancer-Related Fatigue (Ryan Halvorson, 2008)

b)The advantages of exercising is that it helps build and maintain healthy bones,muscles and joints, it can ward off diseases. It can also prevent muscle cramps. Exercise controls weight. Exercise improves mood. Exercise boosts energy.

c)Hence, some possible solutions is to exercise regularly with different kinds of exercises every day. This could help build stronger muscles in those areas. Another way is to be involved in sports not only improve physically, but mentally and intellectually.

2. Reasons for choice of topic
We have chosen this topic, as we want to find out more about how exercise affects our health. It is said that regular exercise helps in boosting the immune system and Insulin sensitivity is decreased due to exercise (Home Remedies, 2009).

This allows us to fulfil the requirements of the project task as the project task looks at the effects of not exercising, exercising and over-exercising, which is also what we will be doing.

This topic benefits the society as people will know the limits of exercising.

3. Feasibility of the research
There is a need for our research, as many people do not exercise regularly and get really unfit and unhealthy, especially many adults. Hence, our research can help to let these people know that they need to exercise in order to stay healthy and fit.

It is possible to carry out and complete the project, as there are many adults in the neighbourhood to interview and to survey. The proposed course of action is logical and realistic as it can be completed with the help of adults who would be willing to do a survey and with our hardwork and group effort.

The research provides sufficient opportunity for generation of ideas, as we will constantly have to think of ways to do certain things in the project. As for analysis and evaluation of ideas, we will certainly have many opportunities to analyse information and evaluate ideas on how to go about deciding what to do next.

4. Manageability of the research
This task is fairly difficult as it is hard to get solid evidence and statistics easily. However, through surveys and interviews from outside, it is a challenge but not impossible. We can look up on the net for suggestions and information on the topic

5. Accessibility of the information required
Information/knowledge that will be relevant to our research would be the amount of time people usually spend on exercising on average each day.

We will be obtaining this information from primary and secondary sources, depending on which one gives more reliable and useful information. Some alternatives that we have thought of would be to ask others for information or where can we find the information that we need (e.g. the Internet).

Some problems we anticipate while gathering my materials would be that the information that we can find is not entirely relevant to our project and that that is already the closest piece of information among all others that we have found.
