Function name:
VARA

Category:
Statistical Analysis

Summary:
Calculates the sample variance of a set of numbers. The value of text is 0.

Syntax:
VARA(Number 1[; Number 2[; ...[; Number 255]]])

Returns:
Returns a non-negative real number which is the estimated sample variance based on the numbers passed in the arguments.

Arguments:
Number 1, Number 2, ..., Number 255 are numbers, references to cells or to cell ranges of numbers.


 * The parameters should specify at least two values. If there are less than two values, then the function will return a division (#DIV/0!) error.
 * If any of the arguments contain text values either being passed directly then the function returns a name (#NAME?) error and if passed with double quotes then the function recognizes it as text and uses 0 for that value.
 * If a cell contains text, error value, or empty cells, then the function uses the value 0 for them. For logical values, TRUE is considered as 1, and FALSE is considered as 0. However, empty cells are ignored.
 * If a cell contains 0 then the function includes it.

Additional details:

 * The formula for VAR is:

where xi is Number i, n is the count of xi's and x̄ is mean value.
