Learning how to use variables in DAX formulas is beneficial for data analysts because it allows them to simplify their code and make it easier to read and understand. Variables can be used to store intermediate results, making complex calculations more manageable and reducing the risk of errors. Additionally, using variables can help to optimize query performance, as calculations that are reused multiple times can be cached in memory.

Using variables can make it easier to debug code, as it allows analysts to isolate and test individual parts of the calculation. In this tutorial, Sam will demonstrate how you can use variables in your DAX formula with Power BI.
