Description: The FREQUENCY function in DAX (Data Analysis Expressions) is a powerful tool that calculates how often values occur within a specific range. This function returns a vertical array of numbers representing the count of times each value in a dataset falls within defined intervals. FREQUENCY is particularly useful in data analysis, as it allows analysts and users of business intelligence tools to better understand the distribution of data. By using this function, patterns, trends, and anomalies in the data can be identified, facilitating informed decision-making. The function works primarily with numerical data and its output can be used in visualizations and reports to provide a clear representation of value frequency. Additionally, FREQUENCY is an array function, meaning it can handle multiple input values and return multiple results, making it very versatile in the context of complex data analysis.
