DAX Statistical Functions

The Data Analysis Expressions (DAX) language includes a wide range of functions that help you refine your queries when retrieving data from a SQL Server Analysis Services (SSAS) tabular database. You've seen numerous examples of DAX functions throughout this series on the tabular model. One set of functions that are particularly useful when working with tabular data are the statistical functions, which support various ways to aggregate and analyze data. Statistical functions include not only the typical standbys, such as Min and Max, but also those that help structure that data into tables, such as AddColumns and Summarize.
