Question

the coefficent of variation of certain data is 5 and mean is 60. find the standered deviation​

Answer 1

Answer:

300

Step-by-step explanation:

Given data

mean = 60

coefficient of variation = 5

Let standard deviation be k.

Now, by formula ,  $\textrm {coefficient of variation}  = \frac{\textrm{standard deviation}}{\textrm{mean}}$

Putting the values we get,

5 = $\frac{k}{60}$

or, k = 5 x 60 = 300

So, standard deviation is 300.
