Uncovering outliers in your data with Explain Data
Explain Data is a feature in Tableau that allows users to find outliers in their data through the automatic creation of potential explanations presented visually. When you use Explain Data on an individual mark in a Tableau visualization, Tableau builds these potential answers using statistical models that include data from the data source that isn’t in the current view.
Unless you instruct it otherwise, Explain Data will use all the columns in your data source to try to find explanations. Unlike Ask Data, the additional data modeling for Explain Data occurs in the workbook. This means Explain Data works with both published and embedded data sources.
In the next section, we will see Explain Data in action and control how it works by deciding which columns (fields) we want to exclude from the analysis.
