About our study: Purpose
The purpose of our project is to see if there is a relationship between a person's cumulative GPA (grade point average) and horoscope sign. We intend to see if individuals born under certain astrological signs are more intelligent than others. Our goal is to determine if people born during a specific season are more likely to have a higher mean GPA.
We thought it would be interesting to see if there was a relationship between the season a person was born, and their grade point average. We did not find much background information that related to our topic. We google searched multiple phrases, and did not find much. We did find some studies that found that children born in the spring months tend to be smarter at a young age. Some studies found that this has to do with climate in which the person is born.
We then decided to conduct a survey to see what astrological sign and person was and what their GPA is. To do this, we selected 80 random students that attend North Olmsted High School. We created a survey that asked what the person’s sign and GPA. We sent them a survey with a post-it note, so the survey would be anonymous.
Once we received the surveys, we separated them into groups based upon the seasons of the year. We also put each person’s GPA into a category. We then entered the data into Minitab. Once the data was in Minitab, we ran a test statistic on the data. We also conducted a chi-square test to see if there was a relationship between the season a person is born and their GPA. After running the chi-square test, we discovered that the test could not be done, since the expected cell counts were less than five. Therefore, we could not conclude if their was a relationship between the two.
If we were to do this study again, we would have selected a larger sample size. Also we could have pick random people from each season, rather than picking any student in the high school. Instead we should have separated the students of North Olmsted High School by their birth month, then sent random surveys to those students.
