1. AP Statistics Final Project Philadelphia Phillies Attendance Kevin Carter, Devon Dundore, Ryan Smith

2. Oldest one-named, one-city franchise in all professional American sports First game played on May 1, 1883 2 World Series Victories (1980, 2008)

3. Built in 2004 43,651 seats Sold out 73 times in 2009 Biggest attendance 46,208 2008- Celebrated first World Series since 1980

4. Studied Phillies attendance from 2004- 2009 depending on… - Weather (temperature) - Time of day Calculator randomly select 10 games from each season Look up time of first pitch and park attendance of past games using www.baseball-reference.com and www.fairview.wswww.baseball-reference.comwww.fairview.ws

5. Create scatter plots of comparisons to view LSR and correlation Conduct a 2 sample t confidence interval for each comparison of statistics Also, conduct a 1 sample t confidence interval of the average attendance at Citizens Bank Park

8. Correlation=.04622 Coefficient of Determination=.0021 LSR: Attendance=30.0423(Temperature)+35012 -Weak (scattered) -Very slightly positive Residual plot is scatter so LSR is a decent fit

9. .21% of the change in attendance is due to the change in temperature Temperature seems to have practically no relationship or effect on Phillies game attendance

12. Correlation= -.118 Coefficient of determination=.014 LSR: Attendance= -419.731(Start)+44841 -Weak (slightly scattered) -Slight negative slope Residual Plot is scatter so LSR is a good fit

13. 1.2% of the change in attendance is due to the change in start time of the game Start time seems to have practically no relationship or effect on Phillies game attendance

14. Use linear regression t tests for both comparisons to test the hypothesis that… Beta= 0 or Beta>0 (temperature) Beta=0 or Beta>0 (time of day)

15. STATE -SRS -True relationship is linear CHECK -Checks out -Assume (scatter plots) *Sample size of 60 games

16. t= b/SE b t=.3524 (df=58) P(t>.3524|df=58)=.36.36>.05 so… We fail to reject the null hypothesis because the p-value is greater than.05. We have sufficient evidence that the slope of the LSR line is not greater than zero. The weather does not have a great effect on Phillies game attendance.

17. Mean+/- t-score(Stand. Dev. of Stat.) = (35201.9, 39256.2) We are 95% sure that population difference of means lies between 35201.9 and 39256.2 people attending the game.

18. STATE -SRS - True relationship is linear CHECK -Checks out -Assume (scatter plots) *Sample size of 60 games

19. t= b/SE b t= -.9085 (df=58) P(t>-.9085|df=58)=.82.82>.05 so… We fail to reject the null hypothesis because the p-value is greater than.05. We have sufficient evidence that the slope of the LSR line is not greater than zero. The start time of the game does not have a great effect on the Phillies attendance.

20. Mean+/- t-score(Stand. Dev. Of Stat.) = (35260, 39314.6) We are 95% sure that the population difference of means lies between 35260 and 39314.6 people attending the game.

21. Attendance can be affected by other things (team being played, pitcher, star ball players, promotions, ticket pricing) Phillies were better and more popular during some year than others Data included many more night game times than afternoon games

22. Personal Opinions We would have thought that our data would have a had a better correlation. We feel that our own decisions to go to a game is somewhat effected by time and temperature. (Rainy day = colder weather) We feel that there was to much bias to our data.

23. Conclusion In conclusion, we can say that time of day and temperature has no relation to the attendance of a Philadelphia Phillies baseball game. Either nothing or something else is effecting the attendance of these games.
