Syntax: CSTDS(argumentlist, C)
argumentlist = any combination of cells or ranges
C = a constraint expression
CSTDS returns the sample standard deviation (N-1 weighting) of its arguments which satisfy the constraint C. Blank cells and cells containing strings are not counted.
Examples:
CSTDS(A1..A3, #
10) = 3.2145503, where A1..A3 are 1, 2,
and 7
CSTDS(Y1..Y5, #
25) = 8.1853528, where Y1..Y5 = 22, 24,
29, 34, and 45
