    Survey MAX of

    Alim M



      I need some help with the survey I'm working on.


      I have some data from 2 surveys, Survey A and B.

      I am comparing results of each survey.

      I want to display which survey had highest response number for each answer choice.

      See screenshot.

      Thank you very much.


      P.S. I have attached Excel spreadsheet I'm working with. I'm using Tableau Public.

          Hi Alim,


          LOD expressions should fix give you what you are looking for.  On the left in this screen you can see the original view and on the right the survey code that prevailed. This was good for validation. For simplicity, I created three calculated fields to accomplish this. You could probably combine them though.


          1. surveyA -

                  IF [Survey Code] = 'A' THEN [Measure]


          2. surveyB

                  IF [Survey Code] = 'A' THEN [Measure]


          3. surveySelect - LOD

                    IF { FIXED [Sub-Question #],[Answer Text]: SUM([surveyA])} >

                        { FIXED [Sub-Question #],[Answer Text] : SUM([surveyB])}


                        THEN [surveyA]

                        ELSE [surveyB]



          Hope this is what you are looking for.

            I just caught that the selectSurvey field chooses B over A when they are equal. See 10_5 "likely not purchase". You should add another line of logic to catch those.

              Hi Eric,

              That's exactly what I was looking for, thank you.


              I have a follow-up question if you don't mind.


              Let's say I want to accomplish the same objective, but instead of displaying individual answers I want to compare the sums of  "Definitely Purchase" and "Likely Purchase" for each sub-question.


              I have tried adjusting surveySelect LOD expression by removing [Answer Text] but the result is not 100% accurate. See screenshot. Any suggestions?


              IF { FIXED [Sub-Question #] : SUM([SurveyA])} >

                            { FIXED [Sub-Question #] : SUM([SurveyB])}


                            THEN [SurveyA]

                            ELSE [SurveyB]
