Question: You have landed a job with a sports psychologist, & presently find yourself involved in testing the effectiveness of fumble prevention training for running backs. You select twenty running backs & pair them according to how many fumbles they lost last season. Then you take each pair & randomly assign one to each of two fumble prevention training programs. Thus, your subjects are matched on fumble proclivity. Below find three columns-pair number, fumbles lost in the ten games after the training for method one & fumbles lost in the ten games after the training for method two.
