Question

If the variance of the data values in a population is 196, what is the standard deviation of the data values?

Answer 1

the standard deviation is the square root of the variance

so if the variance is 196, then the standard deviation is the sqrt of 196, which is 14

Answer 2

14.

Explanation:

It is given that the variance of the data values in a population is 196.

Population variance =
`\sigma ^2=196`

We need to find the standard deviation of the data values.

Population standard deviation =
`\sigma`

`\text{Population standard deviation}=\sqrt{\text{Population variance}}`

`\sigma=√(196)`

`\sigma=14`

Hence, the standard deviation of the data values is 14.
