Comparing obesity among different races
The hypothesis that there is a higher percentage of obese African-Americans teenagers between ages 15 and 18, compared to Caucasians of the same age, is proven to be true.
The main treatment for obesity is the control of food intake by dieting and burning of calories by exercising. This is normally supplemented with medication to reduceone’s appetite and decrease the percentage of fat absorbed. Sometimes surgery is also performed to help a patient reduce weight.
For more reliable results, we should conduct the survey across several schools as well as several towns/cities. The results for a particular school or even a particular town/city may deviate from the norm.
Compare the rate of obesity amongst Hispanic-Americans and African-Americans.
You could also compare the waistlines of the participants.
