The basic equation is as follows:`Net run rate = (number of runs scored/number of overs faced) - (number of runs conceded/number of overs bowled)`
A positive net run rate means a team is scoring faster than its opposition overall, while a negative net run rate means a team is scoring slower than the teams it has come up against. A positive NRR is therefore desirable.
NRR is usually employed to rank teams that have finished a series or tournament on the same number of points.
Examples: In the 2012 Indian Premier League (IPL), Pune Warriors scored 2321 runs off 319.2 overs and conceded 2424 runs off 310 overs. Pune Warriors' NRR is therefore:(2321/319.333) - (2424/310) = 7.268 - 7.819 = -0.551
If a team is bowled out before completing their full quota of 20 or 50 overs (depending on whether it is a Twenty20 or one day match), that full quota is used in the net run rate calculation. For example, if the team batting first is bowled out for 140 after 35...
