3.  We realize that alcohol can play a huge role on the performance of a college student. We conducted a survey with 13 questions which asked 75 business students questions about how much alcohol they consume and how it effects their schoolwork.

4.  The college we chose was Cal State University San Marcos.  We chose to give the surveys to students attending classes in the College of Business.  We conducted 75 surveys in various classes.

Has drinking caused you to be absent in class this semester? If so, how many times? Has drinking caused you to miss assignment deadlines this semester? If so, how many times? Have you ever had alcohol on campus? Have you ever been intoxicated while in class? If so, how many times? What is your current grade point average?

6.  For our research, we decided to answer the question whether or not alcohol affects students’ performance in school. We set out to find if there is any correlation between various alcohol related factors and students’ GPA.  Null Hypothesis: Students who drink more than 5 nights a week will have a GPA lower than 3.0.  Alternative Hypothesis: Students who drink more than 5 nights a week can have a GPA higher than 3.0.  H ₀ = µ ≤ 3.0  H A = µ > 3.0

13. Out of the 75 surveyed students: The average GPA of the 10 students who have been arrested was 3.025 The student that was arrested the most times (4) had the lowest GPA of the group (2.70)

14. There is a negative correlation between students GPA and the number of classes they miss due to alcohol. As the number of missed classes rises, GPA decreases.

19.  There is a positive relation between the number of nights a student drinks, and their GPA.  When comparing these results to our hypothesis, we found that the number of nights a student drinks during a week did negatively affect students’ GPA.  As the number of nights per week a student drinks, the more their GPA decreases.

21.  We completed a regression analysis comparing the number of nights students drink alcohol to their GPA.  The dependant variable (y) was the students’ GPA  The independent variable (x) was the number of nights students consume alcohol in a week.

24.  Overall, we concluded to not reject our null hypothesis.  Over 57% of the students who drank over 5 nights a week have a GPA of less than 3.0.

25.  Next time would improve:  By increasing our sample size.  Have more specific questions; not using ranges.  Ex. (1-2 drinks, 3-4 drinks)  Decrease the amount of questions in our survey.  Lastly…

26. Make sure you team up with reliable teammates, who don’t drop the class with one week left of school. Ex. Photo courtesy of Ashty’s myspace
