FTEST function

The FTEST function is one of the statistical functions. It is used to return the result of an F-test. An F-test returns the two-tailed probability that the variances in array1 and array2 are not significantly different. Use this function to determine whether two samples have different variances.

Syntax

FTEST(array1, array2)

The FTEST function has the following arguments:

Argument	Description
array1	The first range of values.
array2	The second range of values.

Notes

Text, logical values and empty cells are ignored, cells that contain zero values are included. If the number of values in a data range is less than 2 or a variance of an array is 0, the function returns the #DIV/0! error value.
