Phase TWO: Juul Habits of Flagler College Students in Spring 2019
Introduction:
On the first phase of the project, the Juul habits of a sampled 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 do Juul and the sample of Flagler College students who do not Juul. For purposes of this report, the two samples will be defined with a simple phrase. The term “Juuling Students” will define the sample of those Flagler College students who do use a Juul and the term “NonJuuling Students” will refer to the sample of those Flagler College students who do not use a Juul. There are 54 NonJuuling Students and 46 Juuling Students sampled.
Students surveyed answered many other questions. They reported the number of friends they have who use a Juul, if students think Juuls should be banned on campus, and if they find fruit flavors to be less harmful. First, a comparison will be made between number of friends who use a Juul between the Juuling and NonJuuling Students. Then the responses to whether or not Juuls should be banned on campus and if students find fruit flavors less harmful compared between the Juuling Students and NonJuuling students.
Comparison #1: Number of Friends Who Used Juul
The following stacked boxplots and corresponding summary statistics represent the number of friends who Juul for the Juuling and NonJuuling Students.
Overall, there was a difference in the reported number of friends who use Juuls between the Juuling and NonJuuling Students. The median number of friends who use a Juul for the Juuling Student was 10 friends while the median number of friends who use a Juul for the NonJuuling students was 1 friend. This is a significant difference. The upper and lower quartiles for the sample were different (at 5 and 25 friends for Juuling Students and at 0 and 4 friends for NonJuuling Students) and the minimum and maximum number of friends was the same (at 0 and between 25 friends respectively). The NonJuuling Student sample had outliers. The upper fence for the NonJuuling Student was 10. However, 4 outliers are present at 12, 15, 20, and 25 friends. The upper fence for the Juuling Student remains high at 25 friends. Furthermore, the variability of the Juuling Student is more than that of the NonJuuling Student based on the IQR of both samples (IQR of 20 for Juuling Student and IQR of 4 for NonJuuling Student). Therefore, it seems that the Juuling Students tend to have more friends that use a Juul rather than the NonJuuling Students.

Comparison #2: Bar Plot with Data  Juuls on Campus
The following split bar plot shows that Juuling Students and NonJuuling Students were different in their responses to whether or not Juuls should be banned on campus. Approximately 65% of Juuling Students believe Juuls should not be banned on campus, while 35% of this sample believe Juuls should be banned on campus. On the other hand, approximately 38% of NonJuuling Students believe Juuls should be not be banned on campus, while 62% of this sample believe Juuls should be banned on campus. Based on these results, Juuling Students are more likely to believe Juuls should be allowed on campus, while NonJuuling Students are more likely to believe Juuls should be banned on campus. This result is to be expected.

Comparison #3: Less Harmful Juul Flavors
The following contingency table compares the responses to whether or not students found flavored ecigarettes less harmful than tobacco flavored ecigarettes between the Juuling Students and NonJuuling Students. Overall, 122 out of 150 students surveyed believe that flavored ecigarette are not less harmful than tobacco flavored while 28 believe they are less harmful. Thus, 81.3% (122/150) of all the students surveyed believe that flavored ecigarette are not less harmful than tobacco flavored. Therefore, the majority of students surveyed feel that flavored ecigarettes are not less harmful than tobacco flavored ecigarettes.
Of the 81 NonJuuling students surveyed, 66 feel flavored ecigarettes are not less harmful than tobacco flavored ecigarettes and of the 69 Juuling Students surveyed, 56 feel flavored ecigarettes are not less harmful than tobacco flavored ecigarettes. That is, 81.5% (66/81) of the NonJuuling Students feel flavored ecigarettes are not less harmful than tobacco flavored ecigarettes while 81.2% (56/69) of the Juuling Students feel flavored ecigarettes are not less harmful than tobacco flavored ecigarettes. Thus, approximately only .3% more of the NonJuuling Students find flavored ecigarettes not less harmful than tobacco flavored ecigarettes. This concludes that there is an almost exact opinion that flavored ecigarettes are not less harmful than tobacco flavored ecigarettes between these two groups.

Conclusion
In this comparison of the opinions between the students surveyed who use a Juul (Juuling Students) and those students surveyed who do not use a Juul (NonJuuling Students), it was found that these two groups differ in the number of friends who Juul and whether or not Juuls should be banned on campus. More of the students who do not use a Juul (NonJuuling Students) had a less number of friends who use a Juul and were more likely to believe Juuls should be banned on campus. On the other hand, more of the students who do use a Juul (Juuling Students) had more friends who use a Juul and were more likely to believe Juuls should not be banned on campus. This was not a surprising find to us. However, the two groups did not differ on whether or not flavored ecigarettes are less harmful than tobacco flavored ecigarettes. Overall, Juuling Students and NonJuuling Students both recognize that flavored ecigarettes are not less harmful than tobacco flavored ecigarettes, but Juuling Students are more likely to have friends that Juul and are likely to believe Juuls should not be banned on campus.
