The AVERAGEX function in DAX is used to calculate the average of a set of numeric values in a table or expression that results in a table. It is useful in Power BI reports when you need to calculate an average for a group of values based on a specific condition, such as average sales per customer.
To maximize the function, use it with a filtered table or expression, consider using it with other DAX functions, and be mindful of performance with large data sets. This also showcases how adaptable iterating formulas are in DAX. In this video, Sam will showcase how you can utilize AVERAGEX for calculating averages per weekdays.
