PHASE 2: Flagler College Students and Marijuana Laws Spring 2019
Mail   Print   Twitter   Facebook


In the first phase of our project, we surveyed 150 statistics students at Flagler College about Marijuana laws, comparisons were drawn between the similarities between tobacco, tobacco and marijuana. In phase two of the report, we are using the sample of 150 Flagler College students but divided into two smaller samples. The samples we are going to use are students opinions as to if alcohol and tobacco are equivalent to marijuana. We are going to use key terms in this report when comparing the two samples. The sample for students who think marijuana is different from tobacco will be No and the other who think it is equivalent is Yes.

Overall, 73.3% of the 150 students surveyed answered that smoking marijuana is not equivalent to smoking tobacco. The percentage of students who answered that smoking marijuana is equivalent to smoking tobacco added up to be 26.3%. Therefor, a majority of students surveyed stated that marijuana use is not the same as smoking tobacco.

Survey Questions

  1. What gender are you?

  2. What is your current age?

  3. Have you ever smoked marijuana?

  4. How many times have you smoked marijuana?

  5. Is marijuana the same as alcohol?

  6. Is marijuana equivalent to tobacco?

  7. What is your stance con medical marijuana?

  8. SHould one be legally able to grow and use marijuana?

  9. What is the maximum number of grams one should on a weekly basis?

  10. Do you support the legalization of marijuana?


Our first dataset was constructed in order to measure the statistics students who believe that marijuana use is equivalent to tobacco use. Our bar graph shows that 110 of the students surveyed fall into our “No” category, the students who do not think marijuana use is equivalent to tobacco use. The remaining 40 students fall into the “Yes” category, meaning they do think marijuana is equivalent to tobacco. The Y axis represents the percentage of students who fall into the yes and no categories. Overall, a higher percentage of students responded with “no,” making up 73.3% of the total students surveyed. Students who responded with “yes,” on the other hand, made up 26.7% of the sample. In this graph it is considered simple data attribute because there is only one characteristic in common which is if students agree or disagree with the idea that marijuana is equivalent to tobacco.


The following boxplots represent the number of times smoked for those who think

marijuana is equivalent to tobacco (Yes) as well as the number of times smoked amongst those who do not think marijuana and tobacco are the same (No). Those who responded Yes are represented by the boxplot on top and the bottom box plot corresponds to those who responded with No. The mean number of times smoking marijuana for those who think tobacco and marijuana are equivalent is 18.8 times. However, those who said it’s different had a slightly lower mean of 18.72 times.


Our third dataset is the summary statistics regarding the number of times students who think marijuana is/ isn’t the same as tobacco have smoked marijuana. The top row of “No” respondents do not think the two substances are equal, while the “Yes” group thinks they are the same. Those who responded with “No” have a higher IQR and Q3 than the “Yes” respondents. However, the min, max, Q1 and median were equivalent in both “Yes” and “No” categories. According to these summary statistics, those who do not think marijuana and tobacco are equivalent tend to smoke marijuana more often than those who think the substances are the same.


The following chart expresses how the 150 surveyed students who claim tobacco is different than marijuana did not differ from stating additionally that it’s also different from alcohol. The frequency of both groups that state the marijuana is different from the other both substances was 80 which were 110 students. The people of alcohol to be the same and tobacco different was 30. For tobacco equal and alcohol different 15 was the frequency. Additionally the frequency for both groups agreeing that the drugs are the same is 25. The groups differ in percentages but there is no surprise that the highest answer were that both groups claim that marijuana provides different feelings and uses against the other two substances.


These charts provide some what bias opinions because it depends how a student sees the consumption of tobacco, alcohol and marijuana or how they observed the news, family discussions, friends and other contributing factors. The p value is 0.0001 so we cannot accept the null hypothesis of bias opinions about marijuana.


The comparison concluded between the perspectives of 150 flagler college students who were surveyed about Marijuana usage and its comparison to alcohol and tobacco. It determined that the students who claimed that alcohol and tobacco differ from marijuana were most of the people surveyed. They did differ in the amount of times they smoked marijuana people who said it was equivalent was almost the same amount as the other group. It wasn't out of the ordinary that most people from both groups agreed that marijuana is different from tobacco and alcohol.
