Do you know the difference between Calculated Columns and Measures in Power BI?

When you run into a wall in Power BI and feel like you've exhausted the out of the box functionality, that when it's time to investigate what a bit of DAX can do for you.

There are 2 different things you can do with DAX, create a Measure or a Calculated Column.

Calculated columns:

• Stored in the database
• Often used to filter/group data

Measures:

• Computed on aggregates of values
• Computed at query time
• Often used to give a numerical metric

GroupingColumn = if (value<x, small, if(value<y, medium, large))

✅ Figure - Good Example: Nested if statements are a great way to split up your data into groups
