Dax Average Of Measure

For example, you can retrieve a table and then count the distinct values in it, or calculate dynamic sums across filtered tables or columns. It allows a measure to evaluate to different values for different cells in a pivot table even though the DAX expression for the measure does not change. This measure will be used to calculate the total sales price. For example, if you use a filter in a measure, and the measure is used in a PivotTable or PivotChart, the subset of data that is returned may be affected by additional filters or Slicers that the user has applied in the PivotTable. Check out this video to see how to create a measure that performs "Aggregation with Iteration"; which is a fancy way of saying DAX needs to calculate the total sales price for each row, then sum it together. The usual way to do this is to multiply each measurement by a factor that indicates its weight, then sum the new values, and divide by the number of weight units you assigned. Luckily DAX has a few Groupers that can handle this quite nicely. I have a fact table, and I need to know the average total of each 'KEY'.

Most common aggregations, such as those using AVERAGE, COUNT, DISTINCTCOUNT, MAX, MIN, or SUM can be created in a measure automatically by using AutoSum. The usual way to do this is to multiply each measurement by a factor that indicates its weight, then sum the new values, and divide by the number of weight units you assigned.
