STDS, STDEV

Syntax: STDS(argumentlist)
  STDEV(argumentlist)

argumentlist = any combination of numbers, cells, or ranges

STDS returns the sample standard deviation (N-1 weighting) of its arguments. Blank cells and cells containing strings are not counted. The formula is given by:

\begin{displaymath}
\sqrt{ \frac{1}{N-1} \sum_{i=1}^N (x_i - \overline{x})^2 }
\end{displaymath}

STDEV is a synonym for STDS.

Examples:

STDS(1, 2, 7) = 3.2145503

STDEV(Y1..Y5) = 9.2032603, where Y1..Y5 = 22, 24, 29, 34, and 45

STDEV(K6..K10) = 0.79122058, where K6..K10 = 1, .33, 0, -0.66, and -0.99
