Converts Sample Standard Deviations into Population Equivalents

Description

This function converts a sample standard deviation (SD) input into the population equivalent. This code is vectorized to convert several sample standard deviations for univariate distributions of identical sample-sizes, if desired.

Usage

popSD(s, n)

Arguments

s	The sample SD(s) (vector)
n	The sample-size for each SD to be converted (vector)

Value

The population SD(s) (vector)
