PHASE 2: Marijuana Laws Spring 2019
Generated Mar 14, 2019 by istrickland159

Introduction:

On the first phase of this project, the opinions on Marijuana Laws of a sample of 100 Flagler College students from spring semester was explored.  In this phase of the report, this same sample of 100 students will be divided into two smaller samples.  The two samples are the sample of Flagler College students who have smoked marijuana and the sample of Flagler College students who have not smoked marijuana.  For purposes of this report, the two samples will be defined with a simple phrase.  The term “female” will define the sample of those Flagler College students who are female. The term “male” will define the sample of those Flagler college students who are male.

Students surveyed answered many other questions. They reported the number of times they have smoked ever, if they have ever smoked or not, and if they supported the use of recreational marijuana.  In this report, three comparisons will be investigated.  First, a comparison will be made between the reported times students have smoked marijuana or not.  Then the responses to how many times those selected students have smoked or not, and lastly, comparisons will be made based on whether students support or oppose the use of marijuana for recreational use

Comparison #1: Gender and how many times they have smoked

The following stacked boxplots and corresponding summary statistics represent the gender of the students, as well as the amount of time the Students have smoked. One of the female Students stated that she smoked 100 times. This is an outlier because smoking 100 times improbable. Therefore, this student is not included in the sample for this comparison.

Overall, there was a big difference between males and females who smoked. However, because a majority of the students surveyed have never smoked before this places the median of times smoked 0 for both male and female. This is not significantly different.  The lower quartile for both male and female for number of times smoked was at 0. However, the upper quartile for male is higher at 45 and the female and the lower at 4. The minimum number of times smoked is at 0 and the maximum is an outlier at 100 times smoked. We do not include this outlier, so our average maximum number of times smoked for male students is 45 and female students is at 4.  In fact, the upper fence of 45 times smoked for males' students is greater than the female student's number of times smoked at 4 times for their upper fence.   This goes with my intuition that male students will smoke more than female students.

Comparison #2: Gender vs have or have not smoked

The following split bar plot shows that there were the different categories and differentiations of genders that do or do not smoke. The comparison made shows the two genders, male and female when surveyed on whether they have or have not smoked marijuana. Among the comparison of the data, approximately 55% of female confirmed they had smoked marijuana, while approximately 45% of females confirmed they had not. When comparing the male students, it was seen that just over 55% of males confirmed they had smoked marijuana, and 44% of males confirmed they had not. Nearly regardless of whatever category was answered, each one was nearly equal to one another.

Comparison #3: Support v. Opposition of Recreational Use

The following contingency table compares the responses of supporting or not supporting recreational marijuana use from male and female students. Overall, 77 out of the 100 students surveyed believe that recreational marijuana use is acceptable while only 23 students do not.  Thus, 77% (77/100) of all the students surveyed feel that recreational marijuana use is acceptable.  Therefore, the majority of the students surveyed feel that recreational marijuana use is good.

Of the 64 female Students surveyed, 49 of the female students support recreational- marijuana and of the 36 male Students surveyed, 28 support recreational marijuana use.  That is, 76.5% (49/64) of the female Students support recreational marijuana use while 77.7% (28/36) of the male Students support the use of recreational marijuana use.  Thus, approximately a 1.2% more of the male Students support the use of recreational marijuana.  There is barely a difference and therefore there is not a significant difference to be observed.

Conclusion

In this comparison of the opinions between the students surveyed who are male and female, it was found that these two groups did not exhibit an extreme difference in the amount of times in which they smoked, and whether they smoke at all. It was also found that there was little to no difference in opinion of in the support or opposition for the use of marijuana recreationally.  More of the students surveyed who had smoked were of the male category, but by only .9%, a correlation which was mirrored also in those who had not smoked, where the difference was spread by only a .9% difference as well, with the majority leaning to the female category. This data was not surprising, as half of the data plots were similar.
