VAR function
VAR estimates the variance based on a sample.
Syntax
VAR (number1, number2, ...number30)
number 1, number 2, ...number 30 are numerical values or ranges representing a sample based on an entire population.
Note: If
the data represents the entire population, use VARP to compute the
variance. Logical values (TRUE and FALSE) and text are ignored. If
logical values and text must not be ignored, use VARA to compute the
variance.
Example
=VAR(A1:A50)
