PHASE ONE: Flagler College Students and Climate Change

Introduction:

The purpose of the study is to see how familiar students at Flagler College are with the topic of climate change. In particular, this report will look into whether or not the surveyed students believe that climate change is real, if those students are of the opinion that climate change is human made or is a natural cycle of the earth’s climate, how many students agree with the U.S. decision to pull out of the Paris Climate Accord, and how the region the students grew up in affects how they answered the questions.

Data Collection:

In this study, descriptive statistical methods will be used to describe the sample of the students surveyed. The targeted population is students of Flagler College. One hundred MAT 223 Statistics students were surveyed. Since only MAT 223 students were sampled, the sample may not be representative of the population of Flagler College students, so sampling bias may exist. Also, since the data in this report was self-reported, the sample results will likely produce measurement bias.

Survey Questions:

1.       What gender do you identify with?

2.       How old are you?

3.       How familiar are you with the scientific evidence provided in support of climate change?

4.       Did you grow up in a coastal region?

5.       How many times have you experienced a dramatic climactic event such as a hurricane or tornado?

6.       Approximately how many hurricanes do you think threat the U.S. each year?

7.       Do you believe that climate change is real?

8.       Do you believe the frequency and strength of dramatic climactic events, such as hurricanes, is on the increase?

9.       Assuming climate change is real, do you believe the cause is human made or a natural cycle of the earth’s climate?

10.    Do you agree with the U.S. pullout for the Paris Climate Accord?

Sample Data – Graphs and Summary Statistics

Demographics:

In the sample of 100 MAT 223 students, 68% were female and 32% were male. A bar graph displaying the students’ ages is given below. This percent distribution of gender is like the percent distribution of the entire student body at Flagler College. Most students at Flagler are female, and so the mode is female.

 <result1>

The ages are displayed below in a histogram. The distribution is unimodal and right skewed with a possible outlier of 39 years. The best way to measure center would be the median and the best way to measure spread is IQR because it is skewed. The median is 19 years and the IQR is 1.5 years. The typical age surveyed was 19 years old and most of the students were within 1.5 years of 19 years old.

Other Sample Results:

Forty of the students reported that they do not read papers, but they do pay attention to reports about climate change in the news, resulting 40% of those surveyed. While thirty-one of the students reported that they read scientific papers regarding climate change, resulting 31%. Twenty-five students reported that they have little exposure to any scientific evidence of climate change, resulting in 25% of those surveyed. While the minority, four students reported no exposure to any scientific evidence of climate change, resulting in 4%.

 <result4>

Two-thirds of students, sixty-seven, reported growing up in a coastal region, resulting in 67% of those surveyed. While only just a third, thirty-three reported living in other regions, resulting in 33%.

 <result5>

In the histogram below are how many dramatic climactic events students have experienced. The distribution is unimodal and right skewed. The best way to measure the center would be the median because it is skewed and the best way to measure the spread would be IQR. The median is 4 dramatic climactic events and the IQR is 5 dramatic climactic events. The typical number of dramatic climactic events 4 and most was between 0 and 5 events.

 <result6>

 <result7>

In the histogram below are how many hurricanes that people think threaten the U.S. per year. The distribution is unimodal and right skewed. The best way to measure the center is median and the best way for spread is IQR. The median is 5 hurricanes per year and the IQR is 6 hurricanes per year. The typical number of hurricanes per year is 5 and most responses were between 2.5 and 7.5 hurricanes per year.

 <result8>

 <resul9>

The results for this question were an overwhelmingly 97% of students reporting that they do in fact believe in climate change is real.

 <result10>

The results of this question suggest that most students surveyed not only believe climate change is real, they also believe that the frequency of dramatic climactic events is increasing. 93% of the students surveyed report that they believe that there is an increase in dramatic climactic events, which is very similar to the 97% who believe climate change is real.

 <result11>

The results of this question are also similar to the previous two, with 86% of the students surveyed reporting that they believe that climate change is human made. It is interesting when you compare the similar results of the last three questions, because a clear pattern emerges. The students surveyed believe that climate change is real, it’s getting worse and it’s a human-made problem.

 <result12>

Although most of the students surveyed feel that climate change is real and a worsening problem, only 70% reported that they disagree with the U.S. decision to pullout from the Paris Climate Accord.
