Impact of a Superstar

Which player does not fall in line? Using scoring data from two NBA teams, pupils look for outliers. They use the best fit line to help them find the culprit and look for the greatest effect on the correlation coefficient by removing a players' data one at a time. After walking through one data set, scholars use the process to find an outlier in another set of scores.
