Adding a Consistency Measure to Cricket Statistics

Posted in Armchair Ruminations by Armchair Guy on September 22, 2007

Cricket statistics indicating performance for batsmen commonly include the number of innings played, batting average, number of ducks, and scoring rate. One crucially important statistic that is missing from this list is any measure of consistency.

Inconsistent batsmen who tend to score big occasionally can have inflated averages that belie their true worth to the team. Consistency is much more valuable than the number of centuries scored. Thus it is important to include a measure of consistency.

What measures might be good? Variance, absolute deviation and entropy are all decent absolute measures of consistency. At least one of these should be reported along with the other statistics for every batsman.
