Average of a batsman is easy. It’s simply the average of runs. So if a player made 100 runs in the first match, 0 in second and 20 in 3rd match. Total runs he scored is 120 in 3 matches. So his average is 120/3, 40 runs per match on average.
For a bowler, the strike rate is the average number of balls taken by him to get a wicket.
Suppose a bowler balls 6 over in 1 match and gets 2 wickets, go wicketless in 2nd match bowling 10 overs and picks up 1 wicket in 3rd match bowling 4 overs.
The total number of balls he has bowled so far is 36+60+24, 120 balls and he has taken 3 wickets so his strike rate is 120/3 40 balls for a wicket on average.
The strike rate for a batsman is simply the number of runs he has scored per 100 balls. So if a batsman has scored 6 runs in 1 ball, we can say he will score 600 runs in 100 balls, so his strike rate is 600. So the strike rate is the percentage, runs made per 100 balls.
If a batsman has scored 320 runs in 500 balls, in 100 balls he has scored on average 64 runs so his strike rate is 64.
Average for a bowler is the average no runs he has given for a wicket. So if a bowler takes 2 wickets for 70 runs in one match and then 1 wicket for 20 runs in 2nd match. He has total given 90 runs and taken 3 wickets, so his average is 30.
Stay tuned.
