Steady as She Goes: Addendum
Last week, I posted a small regression analysis of year to year correlation of points scored versus points allowed. In the past week, I have been conducting similar analyses for previous seasons. Here are the results:
Correlation of points per game:
2004-2005: .3375
2003-2004: .3740
2002-2003: .3602
2001-2002: .1415
2000-2001: .2625
Correlation of points allowed per game:
2004-2005: .4108
2003-2004: .2935
2002-2003: .3606
2001-2002: .3868
2000-2001: .4159
If I had stopped after the second regression analysis, I would have concluded that offensive and defensive correlation from year to year was essentially random. However, after looking at 5 seasons worth of data, I am inclined to believe that year to year correlations between defense are more consistent that year to year correlations between offense. The correlation coefficient for defense was higher than offense for 3 of the 5 seasons, lower for only 1 season, and almost equal for another. Furthermore, the range for the correlation coefficient for defense was much smaller (.1224) than the same range for offense (.2325). Thus I believe the conslusion I reached last week remains correct (somewhat). Your thoughts?
