Ranking the contributions of Wicketkeepers

As part of the wicketkeeping study initiated at this site, it was necessary to incorporate a ranking system in order to gauge wicket keeper contributions. As mentioned before in an earlier post, due to database restrictions, I can only quantify the contributions of keepers rather than judge them by the byes or catches dropped. I have used 5 different scoring techniques.

• A - (dismissals/Test) * batting average
• B - (batting average/10) + dismissals/test
• C - (batting average – overall average of batting average for all keepers) + ((dismissals/test)-overall average of dismissals/test for all keepers))
• D - (batting average/highest batting average amongst keepers) + ((dismissals/test)/(highest dismissals/test amongst keepers))
• E - (batting average/average batting average amongst keepers) + ((dismissals/test)/(average dismissals/test amongst keepers))

D and E use constants (D using highest average, while E used average batting average) so they give the same order.

30 wicket keepers were used to calculate the average of the batting average and the average of the dismissals/test. The average batting average is 20.09, which the average dismissals/test is 2.95.
