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

Answer:

14.

Step-by-step 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 = $\sigma$

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

$\sigma=\sqrt{196}$

$\sigma=14$

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