Syntax: @CVAR(argumentlist, C)
argumentlist = any combination of cells or ranges
C = a constraint expression
@CVAR returns the population variance (N weighting) of its arguments which satisfy the constraint C. Blank cells and cells containing strings are not included.
Examples:
@CVAR(Y1..Y5, #<25) = 1, where Y1..Y5 = 22, 24, 29, 34, and 45
@CVAR(A1..A3, #<C2*E7) = 6.8888889, where A1..A3 are 1, 2, 7, and C2 = 5 and E7 = 2
