What is the Frequency Distribution Calculator?

The Frequency Distribution Calculator is a tool used to organize raw data into a structured frequency table, showing how often each class interval occurs. It calculates key elements like class intervals, frequency, relative frequency (%), and cumulative frequency, which are essential for understanding data patterns, detecting trends, and preparing histograms or other statistical graphs.

How to Use:

1. Enter Data Values: Input your raw data as comma-separated numbers, e.g., 5, 7, 8, 9, 10, 10, 12.
2. Enter Number of Classes (Bins): Specify how many intervals or bins you want the data divided into. The tool automatically calculates class width.
3. Click “Generate Distribution”: The calculator organizes the data into intervals, counts frequencies for each class, computes relative frequencies as percentages, and determines cumulative frequencies.
4. Review the Table: The output displays a table with class intervals, frequency (f), relative frequency (%), and cumulative frequency, along with minimum, maximum, range, class width, and total frequency. This table is ready for use in charts, histograms, and further statistical analysis.
