BEST FORMULAS TO CALCULATE NRR(NET RUN RATE),STRIKE RATE,RUN RATE IN CRICKET MATCH:
1. TO CALCULATE RUN RATE OF A TEAM IN AN INNINGS:
run rate = (score made) / (overs bowled)
eg:
if INDIA has scored 254 runs in 48 overs then run rate= 5.29167
run rate = 254/48=5.29167
2.TO CALCULATE STRIKE OF A BATSMAN IN THE INNINGS:
strike rate=(runs made by batsman) / (total balls faced)*100
eg:
if chris gayle made 68 runs in 49 balls then,
strike rate= (68/49) * 100 = 138.7755
3.TO CALCULATE NRR(NET RUN RATE)OF A TEAM IN THE SERIES ON THE BASIS OF SOME CONDITIONS:
To calculate nrr on the basis of following conditions:
1. Side that bats first wins
* Team A bat first and set a target of 287-6 off their full quota of fifty overs. Team B fail in their run chase, early losses causing them to struggle to 243-8 in their 50 overs.
* Team A's runrate is \frac{287}{50} = 5.74
* Team B's runrate is \frac{243}{50} = 4.86
* Team A's NRR for this game is 5.74 - 4.86 = 0.88 Assuming this was the first game of the season, their NRR for the league table would be +0.88.
* Team B's NRR for this game is 4.86 - 5.74 = -0.88. If this was the first game of the season, their NRR for the league table would be -0.88.
2. Side that bats second wins
* Team A bat first and set a target of 265-8 off their full quota of fifty overs. Team B successfully chase, getting their winning runs with a four with sixteen balls (2.4 of the 50 overs) remaining, leaving them on 267-5.
* Team A's runrate is \frac{265}{50} = 5.30
* Team B faced 47.2 overs, so their runrate is \frac{267}{47.33} \approx 5.64
* Assuming that Team A and Team B had previously played as in the game in scenario one, the new net run rate for team A would be \frac{287+265}{50+ 50}-\frac{243+267}{50+47.33} = \frac{552}{100}-\frac{510}{97.33} \approx 0.28
3. Side that bats first is bowled out. Side batting second wins.
* Team A bat first and are skittled out for 127 off 25.4 overs. Team B reach the target for the loss of four wickets off 25.5 overs, scoring a single to win the game and end with 128 runs.
* Despite Team A's runrate for the balls they faced being 127 / 25.667 = 4.95 (2dp) because they were bowled out the entire 50 overs are added to their total overs faced tally for the tournament, and Team B are credited with having bowled 50 overs.
* Team B actually scored at a slower pace, however they managed to protect their wickets. Thus, only the 25 .(5/6) overs are added to the seasonal tally.
4. Side that bats second is bowled out. Side batting first wins.
* Team A bat first and set a formidable 295-7 off their complement of 50 overs. Team B never get close, being bowled out for 184 off 35.4 overs.
* As in scenario 2, 295 runs and 50 overs are added to Team A's tally.
* However, Team B, despite facing only 35.4 overs, have faced 50 overs according to the NRR calculations, and Team A have bowled 50 overs.
5. Both sides are bowled out, the team batting first therefore taking the points.
* Team A bat first, and manage 117 off 24 overs on a difficult playing surface. Team B fall agonizingly short, reaching 112 off 23.3 overs.
* In this case, both teams get 50 overs both faced and bowled in the overs column for the season, just as in example 1.
6. The game ends in a tie
* Runs and overs are added as in the examples above, with teams bowled out being credited with their full quota of overs. Thus, the net run rate will always be the same.
