PHASE TWO: Flagler College Students and Climate Change 

Introduction: 

On phase one of this project, the climate change beliefs of a sample of 100 MATH 223 Flagler College students were examined. In this phase of the report, the same sample of 100 students will be divided into two smaller samples. The two samples are the sample of Flagler College students who either grew up in a coastal region or did not grow up in a coastal region. In the sample there are 67 students who grew up in a coastal region and 33 who did not grow up in a coastal region coming to a total of 100.

The students that were surveyed in this report also answered many other questions as well. The students reported how many dramatic climatic events they experienced, if they believe climate change is a human made or natural cycle, and if they agree with the U.S. pullout for the Paris Climate Accord. First, a comparison will be made on the amount of dramatic climatic events experienced between the students who did grow up in a coastal region and students who did not grow up in a coastal region. Next, the responses to whether they believe climate change is human made or a natural cycle and whether they agree with the pullout for the Paris Climate Accord will be compared between the students who did grow up in a coastal region and those who did not grow up in a coast region.  

 

Comparison #1: Dramatic Climatic Events Experienced  

The following stacked box plots and corresponding summary statistics represent the number of dramatic climatic events experienced by students who grew up in a coastal region and those who did not. There was a difference in how many dramatic climatic events experienced by students who did grow up in a coastal region and those who did not. The median events for students who did grow up in a coastal region was 5, while the median for students who did not grow up in a coastal region was 1. The medians are significantly different. Between the two groups, the upper and lower quartiles were different. For the students who did grow up in a coastal region the upper quartile was 7 and, the lower quartile was 3. However, for students who did not grow up in a coastal region the upper quartile was 4 and, the lower quartile was 0. Both sample distributions had outliers. Furthermore, the variability of the responses is the same between the two groups based on an IQR of 4 for both samples. For this reason, it seems that whether the students grew up in a coastal region or not, students who did grow up in a coastal region experienced more dramatic climatic events overall.

Comparison #2: Climate Change, Human Made or Natural Cycle? 

The following split bar plot shows that students who grew up in a coastal region and students who did not grow up in a coastal region really didn’t differ in the responses if climate change is human made or a natural cycle. About 85% in both groups say that they think climate change is a human made cause and about 14% of both groups think that climate change is just a natural cycle.

Comparison #3: Paris Climate Accord Pullout 

The following contingency table compares the responses of students that agree or disagree with the U.S pullout of the Paris Climate Accord between students who grew up in a coastal region and students who did not. Overall, 70 of the total of 100 students surveyed disagree with the U.S pullout of the Paris Climate Accord, but only 30 students agree with the pullout. So, 70% (70/100) of the students surveyed disagree with the U.S. pullout of the Paris Climate Accord. Therefore, majority of the students think that the U.S shouldn’t have pulled out of the Paris Climate Accord.  

Of the 33 students surveyed who did not grow up in a coastal region, 26 disagree with the pullout of the Paris Climate Accord and of the 67 students surveyed who did grow up in a coastal region, 44 disagree with the pullout of the Paris Climate Accord. That is, 78.8% (26/33) of the students who did not grow up in a coastal region disagree with the pullout while 65.7% (44/67) of the students who did grow up in a coastal region disagree with the pullout. So, about 13% more the students who did not grow up in a coastal region disagree with the U.S pullout of the Paris Climate Accord. There isn’t that much a difference between the opinions of the students who did not grow up in a coastal region and the students who did.

Conclusion: 

In this comparison of the opinions between the students surveyed who grew up in a coastal region and the students who didn’t grow up in a coastal region, it was found that in these two groups that the students who grew up in a coastal region have experienced more dramatic climactic events in their life and that they really didn’t differ on their beliefs about whether climate change is human made or just a natural cycle. It was also found out that the two groups did not differ much on the opinions of the U.S. pullout of the Paris Accord.
