Question

If Variance is 81 and Mean is 50 , CV is​

Answer 1

Given :-

• Variance = 81
• Mean = 50

To Find :-

• CV = ?

Answer :-

we know that,

• SD(standard deviation) = √(variance)
• CV(coefficient of variation) = (SD / Mean) * 100.

so,

→ SD = √81 = 9

then,

→ CV = (9/50) * 100 = 18% (Ans.)
