Question

The coefficient of variation of a distribution is 60 and the standard deviation is 21, find the mean.

Answer 1

hey!
the formula of coefficient of variation = standard deviation ÷mean × 100
Let mean = x
put all the values in formula
60 = 21 ÷ x ×100
60x = 21 ×100
x = 2100÷60
x =35 ans
mean = 35
Hope that uhh have understood!
