Survey Results

Introduction

-Does the number of sports you play affect the number of people you sit with at lunch?

I chose this research question because in high school, it is assumed that the jocks are the popular kids in the class. I wanted to see if the athletes in this class did in fact sit with more people at lunch than those who don't play sports.

Methods

-n=22

-I walked around the room and asked anyone that was near me.

Results

-Yes, there is a correlation. But it is a weak positive correlation. There is a relationship between the two variables, but it is very weak.

-r=.22

Conclusion

-My correlation coefficient for my data leads me to conclude that there is a weak positive correlation between sports and size of a  lunch group. Even though some athletes did sit with a high number of people, there were also non-athletes who sat with just as many. A possible third variable would be other extracurricular activities. Non-athletes may sit with just as many people at lunch because they are involved in other activities.

-A weakness in my correlational study would be that there were a large number of athletes that only played one sport. This didn't give me a wide range of data. To fix this, I could have been more specific with the sports. For example, do football players sit with more people than basketball players? Volleyball players? Water polo players?
