Question

If mean is 82.5 and standard deviation is 7.2 find coefficient of variance.

Answer 1

coefficent of variance = SD/mean×100
= 7.2/82.5×100
=8.72

Answer 2

μ is the mean for the population, and which is the same as X Bar in the sample. In other words, we can easily find the coefficient of variation, divide the standard deviation by the mean as well as multiply by 100.

Let us consider, we are given.

Mean is 82.5 as well as stander deviation is 7.2

Coefficient variance =?

As we know that

So here coefficient of variance = SD/mean×100 

We are putting the values
coefficient of variance = 7.2 / 82.5*100
coefficient of variance =8.727
