Phase Two: Juuling Habits of Flagler College Students in Spring 2019
Mail   Print   Twitter   Facebook

On the first phase of this project, the juuling habits of a sample of 150 Flagler College students from spring semester 2019 was explored. In this phase of the report, this same sample of 150 students will be divided into two smaller samples. The two samples are the sample of Flagler College students who have ever juuled and who have never juuled. For purposes of this report, the two samples will be defined with a simple phrase. The term “Juulers” will define the sample of those Flagler College students who believe flavored pods are less harmful and the term “Non-Juulers” will refer to the sample of those Flagler College students who believe flavored pods are just as harmful. There are 88 students who do not juul and 62 students who do juul.

Students surveyed answered many other questions. They reported the number of hours they typically spend on juuling, if they had seen any friends using the juul, and if they believe flavored pods are less harmful. In this report, three comparisons will be investigated. First, a comparison will be made between the reported number of times they juuled between the Juul users and Non-Juul users. Then the responses to between using the juul and the feeling that flavored pods are less harmful will be compared between the Juulers and Non-Juuler Students.

Comparison #1: Times juul has been used per day

The following stacked boxplots and corresponding summary statistics represent the time the juul has been used per day per Juulers and Non-Juulers. One Juuler reported that they used the juul 100 times in one day, we thought this was very shocking!


Overall there were a lot of students that reported using the juul, but did not consistently juul on a day to day basis. The data was wrong because both the medians of juulers and non-juulers were both 0. This is shocking because if you are a juuler you would obviously hit it more than 0 times in a day. The minimum for both juulers and non-juulers is 0, again. The maximum for both juulers and non-juulers is 100. Both sample distributions had outliers, 100. The upper fence for juulers was higher than the upper fence of non-juulers.  In conclusion, the variability of the responses is very similar between the two groups based on the IQRs of 3 and 4 for the samples. Therefore students who said they do not juul consistently, do seem to juul.

Comparison #2: Students who witness juuling

The following split bar plot shows that juulers and non-juulers witness the same amount of people juuling on campus. Approximately 90% of both groups have witness other students juuling and  approximately 10% of both groups have not witnessed another students juuling. This result is very interesting! Regardless of whether or not a student partacts in using the juul, they have definitely seen it, juuling definitely occurs on campus.

Comparison #3: Flavored Pods

The following contingency table compares the responses to flavored juul pods between the juulers and non-juulers. Overall 30 out of the 150 students believed that flavored pods are less harmful. While 120 out of the 150 students did not believe this. Therefore a majority of the students surveyed feel that flavored pods are just as harmful as another juul pods. Of the 88 non-juulers, 16 feel that the flavored pods are less harmful and of the 62 juul users, 14 believe that flavored pods are less harmful.


Result 5: Contingency table ever used juul and are flavored pods less harmful   [Info]

Contingency table results:

Rows: Ever Used JUUL
Columns: Are flavored pods Less Harmful?

Chi-Square test:





In conclusion, we found that students who said they do not juul consistently actually do still use a juul. The data was a little confusing. About 90% of Flagler students have witnessed juuling on campus one time or another. Whether the student juuled or not, they knew that flavored pods are just as harmful as other pods.
