    Help! Create a proportional ztest calculation for "weighted data" in tableau?

    Yamil Medina

      Hi, I am working with weighted survey data and need to create a significant Testing calculation (Please see attached for reference).  This is easy to do in SPSS  and I know how to do the Z-test for unweight data in tableau.

      However, this one is different it needs to be for Weighted data.

       

      My questions are as follows:

      • Can tableau even handle this calculation?
      • Will it be better to use R or a different tool to get this calculation ready at the data source level and then get it in tableau?

       

      If you know any other post that is already discussing or that solved this issue please let me know. In addition, I am open to any suggestions you can find online.
