Power BI DAX Cheatsheet 🚀 1️⃣ Basics of DAX (Data Analysis Expressions) DAX is used to create custom calculations in Power BI. It works with tables and columns, not individual cells. Functions in DAX are similar to Excel but optimized for relational data. 2️⃣ Aggregation Functions SUM(ColumnName): Adds all values in a column. AVERAGE(ColumnName): Finds the mean of values. MIN(ColumnName): Returns the smallest value. MAX(ColumnName): Returns the largest value. COUNT(ColumnName): Counts non-empty values. COUNTROWS(TableName): Counts rows in a table. 3️⃣ Logical Functions IF(condition, result_if_true, result_if_false): Conditional statement. SWITCH(expression, value1, result1, value2, result2, default): Alternative to nested IF. AND(condition1, condition2): Returns TRUE if both conditions are met. OR(condition1, condition2): Returns TRUE if either condition is met. 4️⃣ Time Intelligence Functions TODAY(): Returns the current date. YEAR(TODAY()): Extracts the year from a date. TOTALYTD(SUM(Sales[Amount]), Date[Date]): Year-to-date total. SAMEPERIODLASTYEAR(Date[Date]): Returns values from the same period last year. DATEADD(Date[Date], -1, MONTH): Shifts dates by a specified interval. 5️⃣ Filtering Functions FILTER(Table, Condition): Returns a filtered table. ALL(TableName): Removes all filters from a table. ALLEXCEPT(TableName, Column1, Column2): Removes all filters except specified columns. KEEPFILTERS(FilterExpression): Keeps filters applied while using other functions. 6️⃣ Ranking & Row Context Functions RANKX(Table, Expression, [Value], [Order]): Ranks values in a column. TOPN(N, Table, OrderByExpression): Returns the top N rows based on an expression. 7️⃣ Iterators (Row-by-Row Calculations) SUMX(Table, Expression): Iterates over a table and sums calculated values. AVERAGEX(Table, Expression): Iterates over a table and finds the average. MAXX(Table, Expression): Finds the maximum value based on an expression. 8️⃣ Relationships & Lookup Functions RELATED(ColumnName): Fetches a related column from another table. LOOKUPVALUE(ColumnName, SearchColumn, SearchValue): Returns a value from a column where another column matches a value. 9️⃣ Variables in DAX VAR variableName = Expression RETURN variableName Improves performance by reducing redundant calculations. 🔟 Advanced DAX Concepts Calculated Columns: Created at the column level, stored in the data model. Measures: Dynamic calculations based on user interactions in Power BI visuals. Row Context vs. Filter Context: Understanding how DAX applies calculations at different levels.

Here are 5 key Python libraries/ concepts that are particularly important for data analysts: 1. Pandas: Pandas is a powerful library for data manipulation and analysis in Python. It provides data structures like DataFrames and Series that make it easy to work with structured data. Pandas offers functions for reading and writing data, cleaning and transforming data, and performing data analysis tasks like filtering, grouping, and aggregating. 2. NumPy: NumPy is a fundamental package for scientific computing in Python. It provides support for large, multi-dimensional arrays and matrices, along with a collection of mathematical functions to operate on these arrays efficiently. NumPy is often used in conjunction with Pandas for numerical computations and data manipulation. 3. Matplotlib and Seaborn: Matplotlib is a popular plotting library in Python that allows you to create a wide variety of static, interactive, and animated visualizations. Seaborn is built on top of Matplotlib and provides a higher-level interface for creating attractive and informative statistical graphics. These libraries are essential for data visualization in data analysis projects. 4. Scikit-learn: Scikit-learn is a machine learning library in Python that provides simple and efficient tools for data mining and data analysis tasks. It includes a wide range of algorithms for classification, regression, clustering, dimensionality reduction, and more. Scikit-learn also offers tools for model evaluation, hyperparameter tuning, and model selection. 5. Data Cleaning and Preprocessing: Data cleaning and preprocessing are crucial steps in any data analysis project. Python offers libraries like Pandas and NumPy for handling missing values, removing duplicates, standardizing data types, scaling numerical features, encoding categorical variables, and more. Understanding how to clean and preprocess data effectively is essential for accurate analysis and modeling. By mastering these Python concepts and libraries, data analysts can efficiently manipulate and analyze data, create insightful visualizations, apply machine learning techniques, and derive valuable insights from their datasets.
