What is the Cumulative Frequency Calculator?

The Cumulative Frequency Calculator is a tool designed to help users compute the cumulative frequencies for a given dataset of class intervals and their corresponding frequencies. By calculating cumulative frequencies, it becomes easier to understand data distribution, construct cumulative frequency graphs, and analyze percentiles or medians.

How to Use:

1. Enter Class Intervals: Input the class ranges of your data as comma-separated values, e.g., 0-10, 10-20, 20-30, 30-40.
2. Enter Frequencies: Input the frequency for each class interval in the same order, e.g., 5, 8, 12, 10.
3. Click “Calculate”: The tool computes the cumulative frequency for each class by summing up the frequencies progressively.
4. Review Result: The output shows the total frequency and a table displaying each class interval, its frequency, and the corresponding cumulative frequency, useful for constructing cumulative frequency graphs or analyzing data distributions.
