Stats Summary
Run Rate This is the mean, of the number of runs scored per over, during a match.
   
Over Rate The number of overs bowled per hour. 15 is the required minimum.
   
Strike Rate (Batting) The mean of the number of runs scored per ball faced, expressed in percentage. Good SR is above 75. Great SR is above 100.
   
Strike Rate (Bowler) Mean of the number of overs required to take a wicket.
   
Batting Average The total runs scored by the number of times he has got out. Average taken for: usually for career avg., tournament avg. against opposing team etc.
If the batsman does not get out in the series, he doesn't have an average! (As theoretically, his average is infinite)
   
Bowling Average The total runs scored of a bowler before he gets a wicket. Avg. taken: (same as batting avg.). In a series if a bowler does not take a wicket he does not have an average.
   
Economy Rate Runs scored off a bowler per over. Below 4 is excellent
   
Net Run Rate This is the run rate scored by the winning team subtracted by run rate scored by losing team. The winning team gets positive value, losing team the negative value. In a series, the mean of the NRR for all matches played by the team is taken.
   
Batting Innings The number of times the batsman has batted in a match. This is always less than (or equal to) the matches played, but not batted.
