Textbook Problem

Is it possible to obtain a negative value for the variance or the standard deviation?

To determine

**To check:** Whether there it is possible to obtain the negative value for the variance and standard deviation.

Explanation

**Justification:**

The variance and standard deviation are commonly used techniques for measures of variability and both of these measures are based on the similar idea that each score can be described in terms of its deviation or distance from the mean.

Here, the variance is the mean of squared deviations...
