Daily DAX : Day 384 AVERAGE

Power BI DAX: AVERAGE Function

Function Syntax

AVERAGE(<column>)

Description

The AVERAGE function calculates the arithmetic mean of the values in a column, ignoring any BLANK values and non-numeric entries.

Returns: A decimal number representing the average of all numbers in the specified column.

Use Case

Use AVERAGE when you want to find the typical value in a dataset, such as:

  • Average sales per transaction
  • Average customer satisfaction score
  • Average employee performance rating
  • Average delivery time in days

Example

Suppose you have a table SalesData with the following data:

SalesID Amount
1 100
2 150
3 200
4 BLANK

DAX Measure:

Average Sales = AVERAGE(SalesData[Amount])

Result: (100 + 150 + 200) / 3 = 150

Result: 150 (BLANK values are ignored)

Important Notes

  • AVERAGE skips BLANK and non-numeric values.
  • Use AVERAGEX to calculate average over a table expression (e.g., average of calculated values).
  • Handles only one column at a time.

Related Functions

  • AVERAGEX(<table>, <expression>) – Average over a calculated expression
  • MEDIAN(<column>) – Middle value
  • SUM(<column>) / COUNTROWS(<table>) – Manual average

Daily DAX : Day 131 SELECTEDMEASURE

 The SELECTEDMEASURE function in Power BI's DAX (Data Analysis Expressions) language is a powerful tool used primarily within calculation groups to dynamically reference the measure currently being evaluated in a report. It’s part of the calculation group feature introduced to streamline complex reporting scenarios and improve maintainability by reducing the need to duplicate measure logic. What is SELECTEDMEASURE? SELECTEDMEASURE is a DAX function that returns a reference to the measure that is currently active or "selected" in the context of a calculation group. It doesn’t take any arguments and is typically used in the expression of a calculation item within a calculation group. This allows you to write generic logic that can dynamically apply to whichever measure is being evaluated in a visual, without hardcoding specific measure names. Syntax SELECTEDMEASURE()     Returns: A reference to the measure currently being evaluated in the report context. Use Case SELECTEDME...

Daily DAX : Day 446 INFO.CSDLMETADATA

Power BI DAX Function: INFO.CSDLMETADATA INFO.CSDLMETADATA` is a specialized DAX function introduced as part of a broader set of "INFO" functions (like `INFO.TABLES` or `INFO.MEASURES`) used for **model introspection**. It allows you to programmatically access the underlying structure of your Power BI semantic model. What does it do? The function returns a table with a single column containing the Conceptual Schema Definition Language (CSDL)  metadata of your model in XML format . In plain English, it exports a highly technical "blueprint" of your entire data model—including tables, columns, relationships, and measures—as a structured XML string. It is essentially the DAX equivalent of the `DISCOVER_CSDL_METADATA` Dynamic Management View (DMV) used in Analysis Services. --- Syntax and Output The syntax is straightforward as it requires no arguments: ```dax EVALUATE INFO.CSDLMETADATA() ``` Return Value : A table with one column and one row. Content : A long string ...

Daily DAX : Day 453 ENDOFWEEK

Power BI DAX Function: ENDOFWEEK Description The ENDOFWEEK function is a Time Intelligence function in DAX (Data Analysis Expressions) used in Power BI. It returns the date that represents the end of the week containing a specified date (typically Saturday, as weeks are considered to start on Sunday by default in DAX time intelligence). Syntax ENDOFWEEK( [, ]) : A column reference (usually from a Date table) or a date expression. Required. : Optional. Specifies the week-ending convention. Default is Saturday if omitted. Examples 1. Basic usage (default: week ends on Saturday): End of Week = ENDOFWEEK('Date'[Date]) For a date like January 8, 2026 (Thursday), this would return January 10, 2026 (Saturday). 2. In a measure for cumulative sales up to end of week: Total Sales to End of Week = CALCULATE( SUM(Sales[Amount]), DATESBETWEEN('Date'[Date], ST...
