You wish to ensure that the findings of a test are indicative of future performance.

The following calculation combines response rates and quantities mailed for both your control and test packages. Using standard significance calculations at either a 90% or 95% level of confidence, the results of your test mailing are evaluated for these significance hurdles. If the results are found to be significant, then there is a level of confidence that similar results would be repeated on subsequent mailings of an equal or greater quantity.

Fill in the blanks and press "Calculate" button below.
