hello everyone!
Err. i need help from you all. its bout my project.
i really hope u all can help me. thanks a lot!

the title of my project is " Obesity Awarenss Campaign".

the questions are:

Obesity can lead to various health problems such as diabetes, heart diseases and stroke. Your school has decided to carry out an " Obessity Awareness Campaign" with the aim to create awareness among students about obesity related health problems.

In this campaign, you are required to obtain the heights and weights of 50 students in Form 4 or Form 5.

     a) Tabulate your data using the following format.



Height (m)

Weight (kg)


















b) Construct a frequency distribution table for the weights obtained using a suitable class interval.


1)      Represent your date from the frequency distribution table by using three different statistical graphs.

2)      Find the mean, median and mode for the weights of the 50 students. Which one of the three is the best measure of central tendency to represent the data? Explain your choice.


c) Calculate the standard deviation of the weights by using three different methods.

    [ NOTE: Include¡± entering raw data into a calculator¡± as a method]


d) What conclusion can you draw from the value of the standard deviation obtains in part c?







Further exploration.


The body mass index (BMI) gives an indication of the physical state of a person as being underweight, normal, overweight or obese. BMI can be calculated by using the following formula.


                                       BMI =                weight (kg)___

                                                      Height(m) x height(m)


The table below shows the BMI and the corresponding physical state of a person:




Below 18.5






30 and above


a)      Calculate the BMI for each student.

b)      Based on the information given the data collected, determine the percentage of students that are underweight and the percentage of students that are obese by drawing an ogive. Represent your findings using statistical graphs and give comments.

c)      As a student, describe the role that you can play to make the ¡°Obesity Awareness Campaign¡± a success.
