Question

Of the standard deviation in 3.2 com, find the variance._________cm

Answer 1

The relationship between variance and standard deviation is shown below:

Standard Deviation is denoted as:

`\sigma`

Variance is:

`\sigma^2`

Given, standard deviation = 3.2

Thus, to find variance, we simply take its square!

So,

`\sigma^2=3.2^2=10.24`
