Question

Which two options describe the standard deviation?


The variance square


The extreme distance from the mean expected from the data points


The square root of the variance.


The average distance from the mean expected of the data.

Answer 1

Answer:

The square root of the variance.

The average distance from the mean expected of the data.

Step-by-step explanation:

Standard deviation is a measure of dispersal. It determines the average distance from the mean expected of the data.

• Variance is also related to the standard deviation
• It is the square root of the variance.
• The dispersion or variation of a set of values away from the mean is the standard deviation.

       

                Standard deviation = $\sqrt{variance}$
