What does the VAR function do in power bi DAX

This recipe explains what does the VAR function do in power bi DAX

Recipe Objective - How to find Variance using Power BI DAX?

Task - Find out the Variance of sales in the superstore dataset.

Access Job Recommendation System Project with Source Code

Step 1 - Open Power BI report

Step 2 - New measure

Go to Fields pane -> Right-click on Dataset -> New measure

Step 3 - Dax query(VAR.P function)

Write down the formula as var_sales = VAR.P([Sales])

This measure will calculate the variance of sales.

In this way, we can find the Variance using Power BI DAX.
