T.TEST

This function returns the probability associated with a t-test.

Syntax

T.TEST(array1, array2, tails, type)

Arguments

This function has these arguments:

Argument	Description
array1	[Required] Array of values in first data set
array2	[Required] Array of values in second data set
tails	[Required] Number of tails
type	[Required] Type of t-test to perform (1, 2, or 3)

Remarks

The tails and type arguments are truncated to integers. The #VALUE! error value is returned if tails or type is non-numeric.

Examples

T.TEST(A1:A17,B1:B17,4,3)

T.TEST({2,2,2,3,4},{2,3,3,4,5},1,2)
