Question

Variance and standard deviation for ungrouped data easy formula

Answer 1

Step-by-step explanation:

Use this step-by-step approach to find the standard deviation for a discrete variable.

Calculate the mean.

Subtract the mean from each observation.

Square each of the resulting observations.

Add these squared results together.

Divide this total by the number of observations (variance, S2).
