Syntax

TTESTM(inprng1, inprng2, outrng, labels, alpha, difference)
TTESTM?(inprng1, inprng2, outrng, labels, alpha, difference)

Inprng1 is the input range for the first data set.

Inprng2 is the input range for the second data set.

Outrng is the first cell (the upper-left cell) in the output table or the name, as text, of a new sheet to contain the output table. If FALSE, blank, or omitted, places the output table in a new workbook.

Labels is a logical value.

• If labels is TRUE, then labels are in the first row or column of the input ranges.
• If labels is FALSE or omitted, all cells in inprng1 and inprng2 are considered data. The output table will include default row or column headings.

Alpha is the confidence level for the test. If omitted, alpha is 0.05.

Difference is the hypothesized difference in means. If omitted, difference is 0.
