When I originally constructed this plot, I did not realize that the categories changed over the years. Originally, there was a category for actress and then later categories for best actress in a leading role and best actress in a supporting role.

This histogram is for the monthly change in percentage market share for both Windows and Mac platorms for data collected betwen February 2006 and January 2008. There are 24 months in the data set and thus 23 changes for both platforms shown in the graph. Notice that the typical change in market share for Windows is negative while the typical change in market share for Mac is positive. Windows is still king, but Mac is making up ground.

Scatter Plot
I computed the difference, "Yards" - "Yards Next", under Data > Compute Expression. I then plotted this difference against Carries (see my shared result). There seems to be a weak relationship (r=0.266) between the difference in yardage totals and the number of carries beyond 370. It is not statistically significant. The only player though to actually gain more yards in the next year (below 0 on the y axis) was Eric Dickerson in the 1983 and 1984 seasons. Note though that he then dropped off significantly between 1984 and 1985. Maybe there is a bit to the curse? It would be nice to have the number of carries in the next year as well. I suppose we could work this out roughly from the average yards per carry and the total yards.
