The maximum bowling speeds, in km per hour, of 33 players at a cricket coaching center are given as follows


Calculate the median bowling speed.


First we construct the cumulative frequency table


It is given that, n = 33


n/2 = 33/2 = 16.5


So, the median class is 100 - 115.


Where, lower limit(l) = 100


Frequency(f) = 9


Cumulative frequency(cf) = 11


and class width(h) = 15





= 100 + 82.5/9


= 100 + 9.17


= 109.17


Hence, the median bowling speed is 109.17 km/h.
