PHASE TWO: Flagler College Students and JUUL Spring 2019
Generated Mar 28, 2019 by lswackhammer866

Introduction:

On the first phase of this project, the JUUL addiction 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 used a JUUL before and the sample of Flagler College students who have not used a JUUL before.  For purposes of this report, the two samples will be defined with a simple phrase. There are 81 Students who have not used a JUUL and 69 Students who have used a JUUL sampled.

Students surveyed answered many other questions. They reported whether or not they knew one JUUL Pod is equal to a pack of cigarettes, the number of friends they have that have used a JUUL as well as the ones that feel that are less harmful.  In this report, three comparisons will be investigated. First, a comparison will be made between the reported number of students who have or have not ever used a JUUL. Then the responses to whether or not a JUUL is harmful and the feeling that one JUUL Pod equals one pack of cigarettes between the number of students who use a JUUL.

Comparison #1: Number of Friends Who Have Used a JUUL

The following stacked boxplots and corresponding summary statistics represent the number of friends that have ever used a JUUL for the Students using a JUUL and the Students not using a JUUL.  Overall, there was not much of a difference in the reported amount of friends who used JUULs between the Students who use JUUL and the Students that do not use JUUL. The median number of friends that use a JUUL was 10 for Students who use a JUUL, while the median number of friends that have used a JUUL was 2 for Students who don’t use a JUUL. This is significantly different.  The upper and lower quartiles for the samples were also significantly different and the minimum and the maximum number of friends who use a JUUL were `exactly the same (at 0 and 25 hours). One sample distribution has an outlier. The students who use a JUUL have more friends that use JUULs than those students who do not use JUULs. This goes with my intuition that the number of students who use JUULs has more friends that use JUULs than the students who do not use JUULs. Furthermore, the variability of the responses is different between the two groups based on an IQR of 5 friends for the students who do not use JUUL and an IQR of 20 friends for the students who us JUUL. Therefore, it seems that the students who use JUUL have more friends that use JUULs.

Comparison #2: Is a Flavored JUUL Less Harmful

The following split bar plot shows that Students who use JUUL and Students that do not use JUUL differ in their responses to whether or not a flavored JUUL is less harmful. Approximately 33% of students that have used a JUUL believe a flavored JUUL is not less harmful, while approximately 13% of students that have used a JUUL believe that a flavored JUUL is less harmful. On the other hand, 42% of students who have never used a JUUL believe that a flavored JUUL is not less harmful compared to the 12% of students that believe a flavored JUUL is more harmful. This is certainly an interesting result. Regardless if a student has ever used a JUUL before or not, the opinion on if a flavored JUUL is less harmful, most students believe that a JUUL is less harmful. JUUL’s have definitely changed how people view nicotine products.

Comparison #3: Students Who Know a JUUL Is Equal To One Pack of Cigarettes

The following contingency table compares the responses of the students that know a JUUL cartridge is equal to a pack of cigarettes between the students that JUUL and the students that do not JUUL.  Overall, 107 out of the 150 students surveyed know that one JUUL cartridge is equal to a pack of cigarettes while only 43 students do not. Thus, 71.3% (107/150) of all the students surveyed know that one JUUL cartridge is equal to a pack of cigarettes. Therefore, the majority of the students surveyed know the risk they are taking.

Of the 81 Students, that have never used a  JUUL before, surveyed, 48 know that one JUUL cartridge is equal to one pack of cigarettes and of the 69 students, that have used a JUUL before, surveyed, 59 know that one JUUL cartridge is equal to a pack of cigarettes. That is, 59.3% (48/81) of the students that have not used a JUUL know that one JUUL cartridge is equal to one pack of cigarettes, while 85.5% (59/69) of the students who have used a JUUL know that one JUUL cartridge is equal to one pack of cigarettes. Thus, approximately 25% more of the students who have used a JUUL know that one JUUL cartridge is equal to one pack of cigarettes. There is certainly a significant difference in the knowledge these two groups possess about a JUUL cartridge being equal to a pack of cigarettes.

Conclusion

In this comparison of the opinions between the students who have not ever used a JUUL and those students surveyed who have used a JUUL, it was found that these groups do not have a significant difference in the number of friends who have used a JUUL, and there was a significant difference between the amount of friends who use a JUUL. The groups of students who use a JUUL have more friends that use a JUUL than the students that do not use JUULs. However, it was found that these groups have a large difference in opinion with the respondents who believe flavored JUULS are not less harmful than the students surveyed who do believe that it is less harmful. This is not surprising to us, because the same chemicals are used whether it may be flavored or not, it is equal to one pack of cigarettes and based on the students surveyed, the majority of respondents knew that.
