By:Jacob Kemble

Matt KellyTaylor Shannon

Mission Statement

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.

Background Information

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.

Hypothesis

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. H₀ = µ ≤ 3.0 HA = µ > 3.0

• 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.

Response of the Correlation regarding number of nights drinking and Students’ GPA’s

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.

Regression Analysis

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.

Correlation Analysis

Conclusion 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.

Improvements 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…

• Make sure you team up with reliable teammates, who don’t drop the class with one week left of school.
