Question

What is obtained by squaring the standard deviation?

Answer 1

Answer:

Variance

Step-by-step explanation:

The standard deviation is related to the variance. The standard deviation measures the variation or dispersion of a set of data and is represented by the Greek letter sigma $\sigma$, while the variance measures how far a set of  numbers are spread out from their average value. The variance is obtained by squaring the standard deviation, so the variance can be found as $\sigma^{2}$
