Question

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

Answer 1

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

Answer 2

Answer:

The coefficient of variance is 8.73.

Step-by-step explanation:

Given information: Mean (μ)= 82.5, Standard deviation (σ)= 7.2.

The formula for coefficient of variance is

$CV=\frac{\sigma}{\mu}\times 100$

Where, CV is coefficient of variance, σ is population standard deviation and

μ is population mean.

According to the given information, the coefficient of variance is

$CV=\frac{7.2}{82.5}\times 100=8.727272\approx 8.73$

Therefore the coefficient of variance is 8.73.
