  3. The Burning Questions • Do players decline in production after signing a new contract? • Does signing with a new team alter production? • 2010-2011 vs. 2011-2012 (after lockout) • 2011-2012 vs. 2012-2013 • Look at Statistics of all players signing a new contract between the two seasons

  4. Is Re-Signing a Factor? • Krustkal-Wallis Test • Minutes per Game (MPG) • Assists per Game (APG) • Rebounds per Game (RPG) • Points per Game (PPG) • Player Efficiency Rating (PER) • 2-Sample T-Test • Minutes per Game (MPG) • Assists per Game (APG) • Rebounds per Game (RPG) • Points per Game (PPG) • Player Efficiency Rating (PER)

  5. Box Plots (2010-2011 vs. 2011-2012)

  6. Box Plots (2011-2012 vs. 2012-2013)

  7. Results 2010-2011 • Minutes per Game (MPG): T=-2.55, P-Value=0.012* • Assists per Game (APG) :T=-1.20, P-Value=0.234 • Rebounds per Game (RPG): T=-2.75, P-Value=0.007* • Points per Game (PPG): T=-2.83, P-Value=0.006* • Player Efficiency Rating (PER): T=-0.82, P-Value=0.416

  8. Results 2011-2012 vs. 2012-2013 • MPG: T=-0.30, P-Value=0.767 • APG: T=-1.29, P-Value=0.199 • RPG: T=1.05, P-Value=0.296 • PPG: T=0.78. P-Value=0.438 • PER: T=1.65, P-Value=0.102

  9. 2010-2011 vs. 2011-2012

  10. 2011-2012 vs. 2012-2013

  11. Kruskal-Wallis Test Results 2010-2011 vs. 2011-2012 2011-2012 vs. 2012-2013 MPG: K=0.19, p-Value=0.662 APG: K=0.96, p-Value=0.327 RPG: K=0.69, p-Value=0.406 PPG: K=0.35, p-Value=0.552 PER: K=2.43, p-Value=0.119 • MPG: K=4.70, P-Value=0.030* • APG: K=3.88, P-Value=0.049* • RPG: K=5.38, P-Value=0.020* • PPG: K=6.24, P-Value=0.012* • PER: K=0.27, P-Value=0.602

  12. Sign-Test Results 2010-2011 vs. 2011-2012 2011-2012 vs. 2012-2013 MPG: θ=-2.300, p-Value=0.0510 APG: θ=-0.1000, p-Value=0.1980 RPG: θ=-0.2000, p-Value=0.0228* PPG: θ=-0.8000, p-Value=0.0761 PER: θ=-0.5000, p-Value=0.1184 • MPG: θ=-1.200, p-Value=0.2460 • APG: θ=-0.1000, p-Value=0.1258 • RPG: θ=-0.1000, p-Value=0.4260 • PPG: θ=-0.6000, p-Value=0.0650 • PER: θ=-0.7000, p-Value=0.1451

  13. Conclusions 2010-2011 vs. 2011-2012 2011-2012 vs. 2012-2013 There wasn’t sufficient evidence to conclude that there was a significant difference because of re-signing or not. Only RPG had enough sufficient evidence to conclude that there was a significant difference in production after signing a new contract • Re-signing was a factor for every statistics except for PER • Not enough evidence for any statistic to say that there was a significant difference in production after signing a new contract
