Like previous time I decided to estimate the cross-correlation between average runs scored in an over and average wickets per over.
The figure below shows color coded correlations between Runs, Average Runs, Wickets and Average Wickets per over. In panel A correlation are shown for the first inning and in panel B correlations are shown for the second inning. Only significant correlations are shown in the colors. For more visual impression in panel C shows total runs versus total wickets in any given over (blue - Ist inning, red - IInd inning). Similarly, panel D shows average runs versus average wickets. The corresponding correlation boxes for panels C and D are also morked with C and in panels A and B.
There are two observations
1) Runs scored in any over is strongly and positively (0.7 in first inning and 0.57 in second inning) correlated with probability of a wicket in that over. This is similar to what I showed for the IPL2009.
2) The Runs scored and Wickets fallen are far more related in the first inning (0.7) than in the second inning (0.57). Any suggestions why one would expect that?
