[MUSIC] In the last lesson, we focused on what calculated fields are used for and how to create new fields. In this lesson, I will cover quick table calculations and show you how to use this calculations to better tell your story. To take the functionality of calculated fields even further, Tableau allows you to do additional calculations on your data after Tableau has completed a query of the data base. Table calculations address data in the cache table and allow you to perform calculations on visible results. So, what does that mean? Once our visualization is rendered, we can ask Tableau to literally look at the results, numbers, bars or plots. And then do math on those visible results. Most importantly, unlike calculated fields that allow you to compare two or more separate measures in your data set, table calculations allow you to compare a singular measure to itself.

Let's begin by opening our superstore dataset and on any worksheet, let's drag the ship date to the column shelf. And then profit to the rows. Now, if we click on the down arrow on our profit field and select Quick Table Calculations, we can see a handful of additional calculations that we can use instead of using the current SUM function. We can change the sum function to a running total, difference, percent difference, percent of total, rank, percentile, moving average, year to date total, compound growth rate, year over year growth or year to date growth. To use any of these functions, simply click on the function you need and Tableau will automatically make adjustments in the worksheet. For example, if we decide to use the running total function, we can now see that our target is showing a running total across all years. After this lesson, you should now understand what calculated fields are used for, how to create new fields and how to use Tableau’s quick table calculations. In the next lesson, we will focus on custom table calculations to analyze your data even further.
