Two One Sided T-Test (TOST) Template

$10.00

Description

This spreadsheet allows the user to perform a Two One Sided T-Test or
TOST testing. This method allows to determine if the two sample groups
are practically equivalent based on a hypothesized difference. Based
on the value of the hypothesized difference, the program performs a
one sided t-test on both ends of the threshold, and if the p-values
comes up as less than alpha for both the tests, we can conclude that
the two samples are equivalent at the required confidence level, based
on the hypothesized mean.

A normal two sample test does not allow the user to make the
determination that the two samples are equivalent. One can only fail
to reject the null hypothesis, and can never accept the null
hypothesis. This spreadsheet allows the user to statistically
determine if the two samples are equivalent based on the chosen
hypothesized difference.
