VAR

Calculates the variance based on a sample.

Sample Usage

VAR(1,2,3,4,5,6,7,8,9,10)

VAR(A2:A100)

Syntax

VAR(value1, [value2, ...])

• value1 - The first value or range of the sample.

• value2, ... - Additional values or ranges to include in the sample.

Notes

• Although VAR is specified as taking a maximum of 30 arguments, Excellentable supports an arbitrary number of arguments for this function.

• If the total number of values supplied as value arguments is not at least two, VAR will return the #NUM! error.

• VAR will return an error if any of the value arguments include text. To calculate variance while interpreting text values as 0, use VARA.

• VAR calculates variance for a sample. To calculate variance across an entire population, use VARP.

• VAR takes the sum of the squares of each value's deviation from the mean and divides by the number of such values minus one. This differs from the calculation of variance across an entire population in that the latter divides by the size of the dataset without subtracting one.
