Batting strike rate is calculated as (No. of runs / No. of balls faced) * 100.
How is bowling strike rate calculated?
Bowling strike rate is calculated as total balls bowled / wickets taken by bowler.
If the bowler has bowled 300 balls and has taken 15 wickets, then the strike rate is
300/15 = 20.
This means the bowler has taken 20 balls to take one wicket.
Bowling strike rate is a measure of how frequently a bowler achieves the primary goal of bowling, namely taking wickets (i.e. getting batsmen out).
Bowling strike rate is defined for a bowler as the average number of balls bowled per wicket taken.
According to this page:
A bowlers strike rate is calculated by dividing the number of balls he or she has bowled by the number of wickets taken with those balls.
For example if a bowler has bowled 2000 balls in his career and has taken 50 wickets, he has a bowling strike rate of 40.00. In other words the bowler has taken, on average, a wicket every 40 balls.
It is simply the number of balls bowled divided by the number of wickets taken.
Bowling Strike rate = Number of balls per wicket (Total Balls Bowled/Total Wickets Taken)
Bowling Average = Runs per Wicket (Total Runs Given/Total Wickets Taken)
Bowling strike rate = (no. of balls / wickets taken).
