Question

Convert 815367.8 into standard deviation and round to one decimal place

Answer 1

The standard deviation is the square root of the variance. In this case the variance is:

`\sigma^2=815367.8`

So to find the standard deviation we need to take the square root of both sides.

`\begin{gathered} \sqrt[]{\sigma^2}=\sqrt[]{815367.8} \\ \sigma=903 \end{gathered}`

The standard deviation is approximately 903.
