    T-Test calculation

    Steve Wexler

      Greetings,

       

      Has anybody here figured out / posted a table calculations that will perform a t-test for significance?

       

      For my purposes I have a percentage of people that answered "yes" to a question in one quarter, and then another percentage that answered "yes" to the same question in the following quarter.  The T-Test calculation the number of survey participants for each quarter as the number will not be the same.

       

      I have a simple Excel spreadsheet that shows how to fashion the calculation.

       

      I have not spent any time (yet) creating a custom table calc with the hope that somebody here has already figured it out.

       

      Thanks much.
