Challenge
Iteration Functions
You will understand the concept of iteration functions in DAX and prepare the environment for the subsequent challenges.
-
Challenge
The MINX Iterator Function
The MINX function calculates the minimum value of an expression over a table. Here, you will determine the minimum annual income for each occupation.
-
Challenge
The MAXX Iterator Function
You will determine the highest annual income for each occupation.
-
Challenge
The SUMX Iterator Function
You will calculate the total annual income per occupation.
-
Challenge
The AVERAGEX Iterator Function
You will calculate the average annual income for each occupation.
-
Challenge
The RANKX Iterator Function
Finally, you will rank occupations based on their annual income.
