The distribution given below shows the number of wickets taken by bowlers in one-day cricket matches. Find the mean and the median of the number of wickets taken.
Number of wickets : | 20-60 | 60-100 | 100-140 | 140-180 | 180-220 | 220-260 |
Number of bowlers | 7 | 5 | 16 | 12 | 2 | 3 |
Assume the mean a = 120 and h = 40
Median class = 100-140; Cumulative Frequency = 28; Lower limit, l = 100;
c.f. = 12; f = 16, h = 40
Thus, the median of the data is 126.25
