Calculating Building Statistics with Basic DAX Measures
Learn to write fundamental DAX measures using aggregation functions like SUM, AVERAGE, MAX, MIN, and iterator functions like SUMX and AVERAGEX, to calculate various statistics.
DAX Function
These concepts all use AVERAGEX. Work through related PBIX exercises, compare the patterns, and submit numeric answers to save your progress.
Learn to write fundamental DAX measures using aggregation functions like SUM, AVERAGE, MAX, MIN, and iterator functions like SUMX and AVERAGEX, to calculate various statistics.
Learn to use the CALCULATE function to override existing filter contexts, enabling comparative analysis of metrics against a fixed baseline (e.g., comparing country-specific values to a national standard).
Learn to create basic DAX aggregate measures like average and count, including the correct application of AVERAGEX when averaging expressions, to analyze film financial data.
Learn how to effectively use the `FILTER` function within an iterator like `AVERAGEX` to perform calculations on a dynamically filtered subset of a table.
Create three complex DAX time intelligence measures: a quarter-over-quarter percentage, a year-to-date percentage against the previous full year, and a three-month moving average of monthly totals.
Understand and apply the DAX CALCULATE function to modify or replace existing filter contexts within Power BI visuals, using various filter conditions including logical operators and string functions.
Learn how to use a disconnected slicer to dynamically influence measure calculations without directly filtering the main data model, and how to apply this to visual titles and conditional formatting.
