USA Today compared the average graduation rates for male football and basketball scholarship players at top-ranked universities. The graduation rates were expressed as a difference between the graduation rate for scholarship athletes and the university’s overall graduation rate for men. A positive number means that the athletes had a graduation rate higher than the overall graduation rate (#2 means 2% higher) and a negative number means the athletes had a lower graduation rate than the overall graduation rate ($2 means 2% lower). Using the same scale, construct a dotplot of the graduation rate differences for football players and a dotplot for the graduation rate differences for basketball players. Comment on the similarities and differences in the two plots.
