    Dimensions, Measures, and Aggregation

    Teresal Lecus


      I am participating in an online class and received the following instructions for completing an assignment.


      "First, place Country in the Rows shelf as a dimension to see what countries are represented in our data set. If you turn that Country pill into a measure, you can aggregate it by Count (Distinct) to see how many countries there are in total."


      I did as requested but, because I am curious, I also aggregated the Country pill in the Rows shelf as a dimension by Count (Distinct) . I got the same answer for both. Tableau is new to me so it is quite possible that I missed an important step or insight along the way, have I? I don't understand why it was necessary to convert the dimension to a measure.  Any light you can shed would be appreciated.


      Thanks for your help.
