Standard deviation measures how number are spread out .Standard deviation is just the square root of variance . The formula for standard deviation can be represented as


\begin{gathered} \text{standard deviation = }\sqrt{\frac{\in(x-\bar{x})^2}{n-1}} \\ \text{note }\in\text{ sign represent summation.} \end{gathered}

So Standard deviation must be greater than or equal to zero because it comes from a square root.

The answer is True.
