Answer 2

If the variance is 0.04, then the value of standard deviation is 0.2

Given :

The variance is 0.04

To find :

The value of standard deviation

Solution :

Step 1 of 2 :

Write down the relation between variance and standard deviation

We are aware of the formula that

$\sf \: Standard \: Deviation = \sqrt{Variance}$

Step 2 of 2 :

Find Standard Deviation

Here it is given that variance is 0.04

Hence we have

$\sf \: Standard \: Deviation$

$\sf \: = \sqrt{Variance}$

$\sf \: = \sqrt{0.04}$

$\sf \: = 0.2$
