2
Purpose We intend to understand: -If fast food causes an increase in body weight for adult men -"For adult men, is the amount of money spent per week on fast food related to body weight?” If no link is found: discuss alternative causes for increased body weight for adult men
3
Study Design A list of adult male individuals was made Each adult male was assigned a number Numbers generated randomly using Excel Each adult man corresponding to the drawn numbers will be surveyed Simple random sample will be achieved Data will be collected with a printed questionnaire asking two questions: 1) How much money do you spend on fast food each week? 2) What is your body weight?

Difficulties/Surprises Opposing interests in research volunteers made topic selection difficult Communication amongst research volunteers Data collaboration Hesitant participants
14
Analysis Critical Value=.396 Correlation Coefficient=.172 Correlation Coefficient shows there was no relationship between the two variables
15
Interpretation and Conclusion Correlation Coefficient=.172 For adult men, the amount of money spent per week on fast food IS NOT related to body weight Potential causes for increased body weight: Physical inactivity Extracurricular activities (video games, television, etc.)
16
Future Studies Obtain larger sample size Replace body weight (lbs.) with the randomly selected individual’s BMI
