Mail   Print   Twitter   Facebook

Introduction:

A data set shows opinions of school shootings amongst Flagler College students in the Spring of 2019. This report will state the demographic of an individual by surveying age, gender, and the type of school (presumably high school). Then, the stats explores how many guns the students are currently concealing and their purpose for carrying, and how many friends they know with guns. Lastly, the data collection inspects how many school shootings the individual has been in and the punishment they know was given to the shooter. This set also shows student's opinions’ on others gun usage and punishment.

Data Collection:

In this first phase of this project, descriptive statistical methods will be used to describe the sample of students surveyed. The targeted population is all the students at Flagler College in Fall semester 2016.  One hundred fifty MAT 223 Statistic students were surveyed. Since only MAT 223 Statistics students were sampled, the sample may not be representative of the population of all Flagler College students, so sampling bias may exist. Furthermore, since the data was self-reported, the sample results will more than likely produce measurement bias as well.

Survey Questions:

1.What is your gender?

2.How old are you?

3.As a highschool student, did you attend a public or private school or were you homeschooled?

4.How many friends do you have that were raised with guns?

5. Have you been removed from school due to a possible school shooting     

6.What is the number of school shootings you’ve experienced?     

7.Was the shooter tried as an adult?

8.Was the shooter executed?

9.Do you conceal and carry?

10.If so, are you concealing/carrying to protect children?


 

Result 1: Bar Plot With Data   [Info]

The gender is defined between male or female. The mode for this categorical graph is female with over 100 individuals identifying as a female. The male follows with just over 40 people identifying as male.

 

Result 2: Histogram   [Info]
Right click to copy

The age of the students surveyed is displayed in this histogram. This distribution is unimodal and right skewed with a potential outlier at over the the age of 40 and 50.  Since the distribution is right skewed, the best measure of center is the median of 18.5 years old and the best measure of spread is the IQR of 1 year. Thus, the typical age of the students surveyed was 18 years old and most students were within 1 year of 18.5 years old.


 

Result 4: Bar Plot With Data   [Info]

The type of school that the students surveyed attended is displayed in the bar chart below. As expected, the majority of students surveyed, at 70.7%%, attended a public school throughout their high school career while the students that attended a private school was 25.3% and students who were homeschooled was just 4%.

 


 

Result 5: Histogram   [Info]
Right click to copy

The number of friends raised with guns is displayed in the histogram below. The distribution is unimodal and right skewed with no outliers. Since the distribution is right skewed, the measure of the best measure of the center is the median of 3 friends raised with guns and most friends raised with guns was between 0 and 2.5. The IQR is 9.

 

Result 7: Bar Plot With Data   [Info]
Right click to copy

Students were either removed from school due to a potential shooting or not. The majority [mode] of students were not removed (86.6%)- yet it is still shocking that around 13.3% of students had to leave their respected school due to a shooter alert.


 

Result 8: Histogram   [Info]
Right click to copy

The number of SS is displayed in the histogram below. The distribution is unimodal and right skewed with no outliers. Since the distribution is right skewed, the measure of the best measure of the center is the median of 5 SS and most SS was between 5 and 7.5. The IQR is 3.

 

Result 10: Bar Plot With Data   [Info]
Right click to copy

Out of the shooters that individuals have experienced, the mode shows that they were mostly tried as adults. This means that shooters tend to be (according to this data set) adults- at 83.3%. 25 people were not tried as adults.

 

Result 11: Bar Plot With Data   [Info]
Right click to copy

Expanding on the last graph- those who are/have been prosecuted for shooting in a school usually do not get executed. Although, the execution rate is still high, with over 46.7% of shooters getting executed. The mode of ‘no’ could be due to the fact that executions in law are becoming more abnormal. The majority of states prefer a life sentence over death

 

Result 12: Bar Plot With Data   [Info]
Right click to copy

About 80% of Flagler students do not conceal and carry a gun. This is reassuring knowing that the majority of the sample given are not carrying a weapon. However, 20% of students have admitted to carrying a gun- which is legal in Florida to conceal and carry.

 

Result 13: Bar Plot With Data   [Info]
Right click to copy

While questioning whether someone would conceal a gun to protect their children- the mode was the answer ‘no.’ This is most likely because the population included the Flagler students- and the majority of them range from 18-21 (which is not typical for birthing children).

 

Result 3: Summary Stats   [Info]

Summary statistics:


ColumnnMeanVarianceStd. dev.Std. err.MedianRangeMinMaxQ1Q3
Age15019.51333318.8689494.34384030.3546730818.53816541819

The average age of a school shooter is around 19. The spread is small due to the IQR being 3. This means that school shooters have more likely to be around the age of 19. Since the median is less than the mean- the graph from these statistics will be skewed right. Or in other words, it is more likely to have a younger school shooter over older.

 


 

Result 6: Summary Stats   [Info]

Summary statistics:


ColumnnMeanVarianceStd. dev.Std. err.MedianRangeMinMaxQ1Q3
Number of Friends raised with Guns1506.506666761.191237.82248240.63870301325025110

While analyzing the number of friends that were raised with guns- the average amount of students came out to 6. This number is larger than the median of 3 which means the graph would be skewed left. The IQR comes out to 9 which means there's a large amount of variability under this topic.


 

Result 9: Summary Stats   [Info]

Summary statistics:


ColumnnMeanVarianceStd. dev.Std. err.MedianRangeMinMaxQ1Q3
Number of SS1506.093333319.1992844.38169880.3577642152502547

The average of school shootings are unfortunately at 6 shootings in a school year. The spread is quite small because it is around 4. This means that the is not a lot of variability amongst the shootings. The median is less than the mean therefore a graph would be skewed to the left, or the number of school shootings is more than 0.
