I am doing an investigation to find out what is the optimal arousal
level someone should be at while taking a penalty kick in soccer.
There are 10 participants. Each participant has taken a penalty under
6 different arousal conditions. Participants have been marked out of 5
for the quality of each penalty kick. Their arousal level was also
taken just before each penalty kick. The mean mark out of 5 has been
find for each participant under each condition, and the mean arousal
level has been found for each participant under each condition. How
should I analyse this to get results and to see what the best arousal
level is?
