Question

The average runs scored by a batsman in 15 cricket matches is 60 and standard deviation of the runs is 15.Find the coefficient of variation of the runs scored by him.

Answer 1

Formula of coefficient of variation is given by
Coefficient of variation = standard deviation/mean × 100

Here standard deviation = 15
Mean = average runs scored by batsman in 15 matches = 60

∴ coefficient of variation = 15/60 × 100 = 100/4 = 25

Answer 2

Solution :-

Given -

Mean = 60 

Standard Deviation = 15

Coefficient of Variation = (Standard Deviation*100)/Mean

⇒ (15*100)/60

⇒ 1500/60

⇒ 25 

So, Coefficient of Variation is 25
