ST_101_Project Zodiac Accidents
Mail   Print   Twitter   Facebook

The data in this project came from a data set from statcrunch.com regarding the number of traffic accidents  associated with drivers of a certain zodiac sign. There were 13 zodiacs (including ophiuchus) represented by the drivers in the data set. The data set consisted of the zodiac signs, the number of observed accidents for each sign, the number of expected accidents for each sign, and the lengths of the accidents. Because I am interested in astrology, I thought it would be interesting to find the correlation between the observed accidents and expected accidents for the zodiac signs.

To examine this question, I constructed a scatter plot showcasing the observed data first with the X= observed accidents and Y=Length and grouped it by zodiac sign. Then I constructed a scatter plot showcasing the expected data with the X= expected accidents and Y= Length and grouped it by zodiac sign. The resulting graphs can be seen below. I found the opposite of what I expected to be true in that the number of observed accidents for each zodiac sign were close in number to what was shown in the scatter plot for the expected number of accidents. I then went to SummaryStats and calculated the correlation between the expected accidents and the observed accidents and got 0.98964411, meaning it is a very high correlation coefficient between the two variables. I stipulate that the number of expected accidents for the zodiacs can be used to fairly accurately predict the number of observed accidents for the zodiacs.

Isn't length here the number of days associated with each sign?
