Count Items Using Tableau Date Parameter Filter

Learn how to count and aggregate items within user-selected date filters. https://www.courses.tableaumasterclass.com In this video, we will create a start and end date filter that allows me to count the number of members available during a certain time of the year. The tricky part is ultimately aggregating the right counts so Tableau returns a single number. This idea came from a calculation I needed to do where the numerator had the number of members who had the # of Assessments/population of members.
