A. Why has obesity in America increased within the last 50 years?

B. I would research this question by first doing a survey and secondly using existing sources.

C. I would conduct a survey that consisted of 100 different questions. The questions would start out asking about the individual's personal background, finances, exercise habits, eating habits, medical conditions and so forth. I would then compile the information, and compare it to the existing information of obesity.

D. To minimize bias and ethical issues I would use generalized questions on the survey wherever possible. I would also have a pre survey conducted among a small to see if they thought any of the questions were bias.
