Bowling Average : Total Run (conceded) divided by Total Wickets taken by a Bowler in an Inning.
A Bowling Average determines how much a bowler concedes in an inning, or a match, or a series, and so on, giving us a fair indication of how costly or cheap he is while picking wickets.
In a bowling figure, scoring shots and errors balls (No balls and wides balls) are included in his Total Runs conceded.
Team’s Bowling Average can also be measured in a similar way, and it is always divisible by 10 wickets (not 11 wickets) in case of all out.
