Answer 2

If the standard deviation of a data is 0.012 then the variance is 0.000144

Given :

The standard deviation of a data is 0.012

To find :

The variance of the data

Solution :

Step 1 of 2 :

Write down the given standard deviation

Here it is given that the standard deviation of a data is 0.012

Step 2 of 2 :

Find variance of the data

We know that for a given set of observations variance is the square of standard deviation.

Hence the required variance of the data

= (Standard deviation)²

= (0.012)²

= 0.000144
