Questions tagged [stdev]

Returns the statistical standard deviation of all values in the specified expression.

STDEV is used when the group of numbers being evaluated are only a partial sampling of the whole population. The denominator for dividing the sum of squared deviations is N-1, where N is the number of observations (a count of items in the data set). Technically, subtracting the 1 is referred to as "non-biased.
