how to IB? Posted July 13, 2014 Report Share Posted July 13, 2014 The subject of my IA is examining a link between an association football player's height and their ability to maintain a "clean sheet" (not letting any balls past). I took a list of 50 professionals, recorded their height and how many clean sheets they had and the number of games they played in the season. BUT, the delta in the heights of the goalkeepers is very small. just 16cm different from the tallest to the shortest (199cm - 183cm).I was wondering if such a small difference would be a problem for calculations and analysis?
