Question

Standard deviation formula for continuous data

Answer 1

Answer:

Non-grouped data is just a list of values. The standard deviation is given by the formula: s means 'standard deviation'. Now, subtract the mean individually from each of the numbers given and square the result.

Answer 2

Answer:

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).
