Standard deviation signifies the distribution of results surrounding a value or result. To offer the appropriate circumstance to adequately interpret standard deviation, you could quite often calculate and show the results if you calculate standard deviation in Excel.

Begin excel either one open document which has information for that you would like to calculate statistics or enter the information in to the empty file.

STDEVS =standard deviation for sample
STDEVPA = standard deviation for population
STDEVA = standard deviation for sample
