1. SOCIAL NETWORKING SITES VS. HOURS ONLINE Alexi-Jo Hanner, Hayley Knepper, and Helen Floran

2. Objective and Hypothesis  Our objective was to discover the relationship between the number of social networking profiles one has and the amount of time one spends on the computer.  If one has more social networking profiles, then one will spend more time on the computer.

3. Description  To collect our data, we interviewed 30 people at DuBois Area High School. Most of the interviewees were students, while some were teachers. We simply asked them how many social networking profiles they had, and the amount of hours they spend on the computer in a day.

5. Scatterplot

6. Correlation and Square of the Correlation  R = 0.4226  We had a weak, positive correlation. It was weaker than we expected. This means there is a very weak relationship between the number of social network profiles and the number of hours spent on a computer.  R 2 = 0.1786  There was a 17.86% variation in our y values. The percent error was 82.14%.

7. Prediction  We predict that if you have 5 social networking profiles, then you will spend 6.3813 hours on the computer in one day.  In relation to our scatterplot, our prediction was close to some of the points on our plot. The point is obviously on the line, since we used the regression line’s equation.  Our prediction isn’t too reliable, since our percent error was 82.14%.

8. Conclusion  There is a very weak relationship between the number of social networking profiles one has and the amount of time spent on the computer.  Possible outliers include teachers who use the computer for work and people who use the computer for gaming.
