Net Run Rate (NRR) is a crucial statistic in cricket, particularly in league formats, used to determine team rankings when points are tied. It represents the difference between the average runs scored per over and the average runs conceded per over by a team. A positive NRR indicates that a team is scoring runs faster than it is conceding them, while a negative NRR suggests the opposite.
The formula for NRR is:
NRR = (Total Runs Scored / Total Overs Bowled) – (Total Runs Conceded / Total Overs Bowled)
When calculating NRR for a team over a season or a series, you sum up all the runs scored, all the overs bowled, all the runs conceded, and all the overs bowled by the opposition across all matches played. It's important to use the exact number of overs bowled, not the maximum overs allocated for a match, as matches can be shortened due to weather.
