Drinking and cheating study
Mail   Print   Twitter   Facebook

In this study, two questions were asked:

Q1. What are the drinking habits of students at this university? In particular, what is the typical number of drinks a student has during a week? Do the data suggest that drinking is a problem in this university?

Q2. One of the statistics professors at this university uses the honor system when giving exams. If there were cheating going on during her exams, would the professor be likely to know about it?

This graph displays the number of alcoholic beverages that students at this university drink per week. With alcohol, at the bottom, ranging from 0-40 drinks per week and the number of students on the left, we can see that many students do not drink at all but we can also see that there are some students that drink up to 36 alcoholic beverages a week.

Result 2: Column Statistics drinking lab   [Info]
Summary statistics:
Column n Mean Variance Std. Dev. Std. Err. Median Range Min Max Q1 Q3
Alcohol 206 4.538835 47.830193 6.9159374 0.4818562 1 36 0 36 0 7
Height 236 66.76589 14.553736 3.814936 0.24833117 67 17 59.5 76.5 64 69.25

This table shows the average amount of alcoholic beverages drank per week (4.5 drinks) along with the max amount (36 drinks) and the median (1 drink). According to the data, this university does have a drinking problem. Although most of the students don't drink at all, there are too many that drink over 10 drinks per week and even some that drink an unholy amount of 36 drinks per week which, I think, constitutes as a drinking problem.

Now moving on to our second question. This pie graph shows us that 91.5% of the student body would not tell their professor that someone was cheating during an exam. With only a shocking 8.5% of the student body that would uphold the university's honor code, it is unlikely that the professor would know about every event in which someone cheated.

In conclusion, the data has shown us that the university does have a clear drinking problem with a lot of their students even though most don't drink at all. The average number of alcoholic beverages that each student drinks is about 4.5 drinks per week which isn't that bad when you think of about it but the only reason the average is that high is because of the few students that enjoy destroying their livers and drink up to 36 alcoholic beverages per week. Without these students taken care of, the university still an overall drinking problem. To answer question two, I would have to say that it is very unlikely for the professor to know about cheating because only 8.5% of the student body would tell him/her about it and even that depends on if that 8.5% saw anyone cheat.
