Net Run Rate
The net run rate ( NRR ) is a statistic that is used in cricket. It is used to distinguish two or more teams finish level on points in the table. The NRR is only in the forms of play makes sense, where the number of the Over is limited, and is used accordingly only there. In international cricket, this particular one-day internationals and Twenty20 International games, but not, for example Test matches. To match its importance after from other sports, such as football or handball, known goal difference.
Calculation
Run rate
The net run rate is the " run rate " basis. This is defined as the ratio of runs scored to the number of overs, in which these runs were scored.
Net run rate
In simple terms, the net run rate is in a game from the perspective of a team, the run rate their own innings minus the run rate of the enemy from its inning. It follows the following formula:
Special
The Over is considered that a statement such as " 26.1 Over" is not to be read as 26 1/10, but, following the usual notation in cricket, as 26 1/ 6 because the number after the point is always the balls of a incomplete overs indicates. Therefore, one can not replace the item by a comma in German.
Should a team lose ten wickets in all their innings before its disposal over of play, do not actually played over into the formula. Instead, the number of the Over is used, the innings was the last wholly recognized. Otherwise, the batting team perversely would benefit from having all their batsmen retire early.
When using the Duckworth - Lewis method (D / L) is not the runs actually achieved and completed over are used for the first innings of the game. Otherwise it could happen, for example, that the losing team a higher run rate in their innings reached as their opponents. If the game was canceled, it was due to the Over completed in the second innings but still be counted, then the " par score " is used at the time of the crash and the same number over, which was completed in the second innings. If D / L applied at an earlier point in the match and then the game could be played to the end, which decreased by one target of the second batting team and the second- batting team last total available number of overs shall be used. The Runs and Over the second batting team go as in all "normal" games in the formula.
Use in group matches
If two or more teams in group games are differentiated, the net run rate each team from all games will be formed, which have been played to a conclusion at the end. Games that are regarded as "No Result", are not taken into account. For this, all runs scored in the group matches completed are added, as well as all over. The same is done for the runs and over the respective opponents and then determined from these four figures, the net run rate of each team. It is thus not formed, the average NRR of all games. A higher net run rate then that means better placement.
Application
As a decision criterion, the net run rate in cricket World Cup has been used for the host in 1992. She pulled it from the run rate previously used and thus took into account not only the performance of a team in hitting, but also of bowling.
