What are some common DAX functions used in Power BI?

As an experienced tutor registered on UrbanPro.com, I understand the importance of Microsoft Power BI in the field of data analytics and business intelligence. In the context of Power BI, Data Analysis Expressions (DAX) functions play a crucial role in performing calculations, creating custom measures, and manipulating data. Here are some common DAX functions used in Power BI that I often cover in my Microsoft Power BI online coaching sessions.

Common DAX Functions:

1. SUM:

   • Description: Adds up all the numbers in a column.
   • Example: Total Sales = SUM('Sales'[SalesAmount])

2. AVERAGE:

   • Description: Calculates the average of a column of numbers.
   • Example: Average Price = AVERAGE('Products'[Price])

3. COUNT:

   • Description: Counts the number of rows in a table or values in a column.
   • Example: Number of Orders = COUNT('Orders'[OrderID])

4. MIN and MAX:

   • Description: Returns the smallest or largest value in a column.
   • Example: Earliest Date = MIN('Date'[OrderDate])

5. FILTER:

   • Description: Returns a table that has been filtered.
   • Example: High Revenue Customers = FILTER('Customers', 'Customers'[Revenue] > 100000)

6. RELATED:

   • Description: Follows a relationship to return the related values in another table.
   • Example: Related Product = RELATED('Products'[ProductName])

7. CALCULATE:

   • Description: Modifies the filter context to evaluate a calculation.
   • Example: Total Sales (Year-to-Date) = CALCULATE(SUM('Sales'[SalesAmount]), 'Date'[Year] = YEAR(TODAY()))

8. IF:

   • Description: Returns different results depending on the evaluation of a condition.
   • Example: Profitability Status = IF('Sales'[Profit] > 0, "Profitable", "Not Profitable")
