What is Net run rate?

Net Run Rate (NRR) is a statistical method used in analyzing teamwork and/or performance in the sport of cricket. It is the most commonly used method of ranking teams with equal points in limited overs league competitions, analogous to goal difference in association football.

The net run rate in a single game is the average runs per over that a team scores, minus the average runs per over that is scored against them. The net run rate in a tournament is the average runs per over that a team scores across the whole tournament, minus the average runs per over that is scored against them across the whole tournament. Note that this is not usually the same as the total or average of the net run rates from the individual matches in the tournament.
A team's run rate (RR), or runs per over (RPO), is the average number of runs scored per over by the whole team in the whole innings (or the whole innings so far), i.e. \text{run rate }=\frac{\text{total runs scored}}{\text{total overs faced}}.

So if a team scores 250 runs off 50 overs then their RR is \frac{250}{50} = 5. Note that as an over is made up of six balls, each ball is 1/6 of an over, despite being normally written in cricket's notation as .1 of an over. So if they got that same score off 47.5 overs, their RR would be \frac{250}{47\frac{5}{6}} \approx 5.226.

The concept of net run rate involves taking the opponents' final run rate away from the team's run rate, i.e. \text{net run rate }=\frac{\text{total runs scored}}{\text{total overs faced}}-\frac{\text{total runs conceded }}{\text{total overs bowled}} .

Usually, runs and overs are summed together throughout a season to compare teams in a league table. A team's overall NRR for a tournament is not defined as the sum or average of the NRR's from the individual matches, but as:

\text{tournament net run rate }=\frac{\text{total runs scored in all matches}}{\text{total overs faced in all matches}} - \frac{\text{total runs conceded in all matches}}{\text{total overs bowled in all matches}}
