I was wishing to understand the formula to use to calculate the Batting Index and Bowling Index in Cricket. This is for limited overs cricket (50 overs) for my club players
The batting index is the Strike Rate multiplied by the Average Runs then that is divided by 50
BI = ((SR*AVG)/50)
E.g. The batting index of a player with SR of 123.4 and an average of 45.33 runs:
(123.4*45.33)/50 = 112 (rounded)
As for Bowlers Index, I'm not sure that exists. Or at least I haven't seen it.
Batting index, at least in the matches telecasted by skysports (the recent t20 between England and India) is a simple addition of a batsman's average and strike rate.
So if a batsman has an average of 23 and a strike rate of 120 , his batting index will be 143.
In the link above there is aline explaining what I said.
