For adult men, is the amount of money spent per week on fast food related to body weight? By: Chad Vigil, Jeannette Watson, Jason Williams, Amanda Webster, Kylee West
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
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?
Variable Statistics for: Amount of Money Spent on Fast Food per Week • Mean: 25.64 • Standard Deviation: 13.5027 • Five-number summary: 7, 16, 25, 31.5, 50 • Range: 58 • Mode: 15, 25, 30 • Outliers: 65
Variable Statistics for:Body Weight of Participants • Mean: 191.48 • Standard Deviation: 29.6944 • Five-number summary: 145, 168, 185, 213.5, 250 • Range: 105 • Mode: 205, 250 • Outliers: none
Regression Analysis • Linear Correlation Coefficient: .172 • Equation for line of regression: ŷ=.3781x + 181.79
Difficulties/Surprises • Opposing interests in research volunteers made topic selection difficult • Communication amongst research volunteers • Data collaboration • Hesitant participants
Analysis • Critical Value= .396 • Correlation Coefficient= .172 • Correlation Coefficient shows there was no relationship between the two variables
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.)
Future Studies • Obtain larger sample size • Replace body weight (lbs.) with the randomly selected individual’s BMI
