we did a single variable regression with some data for one season, using a statistic (like Runs Scored or Runs allowed or Runs Differential) to predict the number of wins a team would get over the course of the season.  I also asked students to do a brief write-up of their results, so you should tell me what league/sport you were examining, write out the equation implied by the regression output, and then calculate the predicted number of wins by a team for a few (3 or so) data points that are reasonable*
