  • The standard deviation is a measure of how widely values are dispersed from the average value (the mean).
  • This function assumes that its arguments are a sample of the population. If your data represents the entire population, then compute the standard deviation using STDEVP.
  • The standard deviation is calculated using the "unbiased" or "n-1" method.
  • Logical values such as TRUE and FALSE and text are ignored.
