# DAXterity

DAXterity is a repository dedicated to practicing and mastering DAX, the formula language used in Power BI for data modeling and calculations. This repository aims to provide a structured environment for learning and experimenting with commonly used DAX functions and patterns.  

> _**80/20 rule, also known as the Pareto Principle, often applies to DAX functions in Power BI. It suggests that 80% of your results can be achieved with just 20% of the functions.**_  

### Frequently Used DAX Functions  

This document provides a categorized list of commonly used DAX functions in Power BI. Use this as a quick reference to improve your data analysis and reporting capabilities.
