In our third of not one<\/a>, not two<\/a>, but three posts on kicking a football in the NFL, we take on a reader question of whether the stadium \/ home team matters for making a field goal. We pulled up the data on every field goal since 2002 (over 10,000) of them and plotted the probability of scoring as a function of the stadium in which the field goal was kicked. The results are above. Bars are +\/- 1 standard error.<\/p>\n Is it a statistically significant effect? Apparently so:<\/p>\n ADDENDUM 1<\/p>\n We had a request to see the broken down by home team or visiting team kicking. Here you go:<\/p>\n \n ADDENDUM 2: Correlation is not causation, but it sure does seem plausible that having an indoor stadium helps the kicker.<\/p>\n \n APPENDIX Figure 1 Data:<\/p>\n Figure 2 Data:<\/p>\n Figure 3 Data: See Figure 1 data plus the comments<\/p>\n Graphs were made in R<\/a> using Hadley Wickham’s<\/a> ggplot2<\/a> package.

\nOwing to the generosity of the great reader \/ Scottish economist Adam Smith (see comments), we now have the stadiums broken down by door (indoor or outdoor). The gray stadiums are either convertible (Houston) or have a small hole in the roof (Dallas). <\/p>\n<\/a>
