Net Run Rate (NRR) is a statistical method used to rank teams in cricket tournaments. It is calculated by subtracting the average runs per over (NRA) conceded by a team from the average runs per over scored by the team (NRS). The formula for NRR is:
NRR = (NRS - NRA) / (total overs faced by the team)
For example, if a team scores 250 runs in 50 overs and concedes 200 runs in 50 overs, then their NRS would be 5 (250 runs divided by 50 overs) and their NRA would be 4 (200 runs divided by 50 overs). So, their NRR would be (5 - 4) / 50 = 0.02.
NRR is a crucial factor in determining the team's position in the league standings, especially when two or more teams have the same number of points. A higher NRR implies a better overall performance of the team in the tournament.
