Selecting moving average time windows

We've seen how to make use of the Tableau interface to create a moving average, but what if we need to create our own moving average calculated field to smooth data?

In this exercise we'll replicate the moving average using the WINDOW_AVERAGE() function and the Market Water Demand GL field.

Specifically, we'll focus on understanding the size of our windows and how this impacts our interpretation.
