So, the standard deviation is the square root of five halves, or approximately 1.58. Were this set a sample drawn from a larger population of children, and the question at hand was the standard deviation of the population, convention would replace the denominator N (or 4) in step 2 here with N−1 (or 3). 3.

The population standard deviation is 2.983. Short term Standard Deviation: The Short-term standard deviation estimates standard deviation within, and is a measure of how widely values are dispersed from the average value (the mean) due only to the effect of white noise.It is used to calculate Short-term Process Capability (i.e.: Cp and Cpk).
