Answer #1

It seems you need to get a data of the survey of certain sample size of the age group of young adults between 18-30 years.

And your topic is  : exercise vs. body fat percentage

Your selection of age group is okay but if convenient you can increase 30 to 50 years also.

and your parameters of measurement variable should be:

Numbers of hours of daily exercise (x) [analysed after one month/week] vs percentage reduction in fat level (y)

You can show a plot also against x and y

Hope it will help you!

Body mass index (BMI), calculated as the ratio weightheight2weightheight2 is often used as an alternative indicator for obesity. A common criticism of BMI is that it assumes the same relative body fat percentage regardless of age, sex, or ethnicity. In order to determine how useful BMI is for predicting...
