Lab | LOD expressions and Dashboards

In this lab you will continue working with the same Tableau workbook from the last lab (lab for 6.2). As a quick reminder, you were using abTesting.csv as well as case_study_ab_test.md files. If you need to give one more look to the case study file, you can find it in the files_for_lab/case_study_ab_test.md.

Instructions

• In this next plot, we want to analyze the customers from group 1 (from the age groups we made from the column clnt_age). The objective is to find and filter out those participants where the account balance is less than the group average. Follow these steps:

  • Create a calculated field with LOD expression as { FIXED [clnt_age (group)] : AVG([Bal]) }.
  • Create another calculated field to store the difference between the average balance for the group and balance for the individual as { FIXED [Client Age]: AVG([Bal]) } - { FIXED [Client Id]: AVG([Bal]) }.
  • Add Client_IDs to the rows. Filter out all the clients other than group_1.
  • Add average balance for each client.
  • Arrange the data in an ascending order of balance.
  • Add the calculated field with the LOD expression.
  • Add the calculated field with the difference.
  • Add filter for the difference values to select only positive values (ie cases where the individual balance is less than the average balance for the group).

• You have plots from the previous lab. Use those plots to create an interactive dashboard for the users
