Question

Coefficient of variant 15 observation 6.8% find coefficient of Standard deviation

Right answer will be follow +30 thanks don't spam ​

Answer 1

Answer:

We know coefficient of variation C. V. = x σ /x *100

ˉ

60=20/x ×100

∴ x =33.33(nearly)

Answer 2

Answer:

The coefficient of variation (C

v

) is defined as the ratio of the standard deviation σ to the mean μ

C

v

=

μ

σ

×100

16=

25

σ

×100

σ=4

Variance = σ

2

=4

2

=16
