The Problem… Does Field Goal percentage and average turnovers per game effect the number of games won during a single season? Thought it was interesting because the Suns are for sale. New owners might be interested in team performance.

Residuals vs. the Fitted Values Response is ln(Wins)
Conclusion Best fits the data is: ŷ = 74.5 - 17.4* TO/Game + 34.4* FG%*TO/Game R 2 value of only 46.8% suggests this model is a poor fit Plots of the transformations indicated that the residuals are not completely random
To answer the question… Yes - field goal percentage and the average number of turnovers per game, during a season, have an effect on the number of games a team wins that season, however additional factors and possibly correlations are necessary to model the data well enough to make future predictions. For future research we suggest another model that includes such factors as Free Throw %, Rebounds, Blocks, Steals or Assists.
