DATA INTERPRETATION Video 17 Tables Venkatesan S IIMB Alumni

Coach Ravi sat with the score cards of his players in the last 3 ODI games where the same squad was retained and the team was all out in all 3 ODIs. Ravi summarized the batting performance through a table, one column for each game. In each column, the three entries provide the number of runs scored by the three top scores from India. The last row in the table denotes the percentage of the total score that was scored by the top three Indian scorers in that game. No two players score the same number of runs in the same game. Ravi also calculated two batting indices for each player based on his scores in the tournaments; the R-index of a batsman is the difference between his highest and lowest scores in the 3 games while the M-index is the middle number, if his scores are arranged in an ascending order.
