I have a set of results where I have the eyesight power of both left and right eyes for each participant (e.g. 0.75, 0.5). Each participant then had to throw basketballs into a hoop and the number of successful throws was recorded.
 
I would like to do two things:
1. Test whether the eyesight power of the left and right eyes are significantly different from each other.
2. Test whether the number of successful throws is significantly affected by eyesight power (i.e. is there a difference between those people who have similar powers in left and right eyesight, to those who have significantly different powers?)
 
I know that I may not have explained this particularly well, but I'm totally stumped as to where to start! I have only had basic lessons with R and now have to do this report! 
 
Many thanks, Samaire
