Cumulative Frequency Calculator
Understanding Cumulative Frequency
Cumulative frequency is a statistical tool used to analyze how data accumulates across ordered values or class intervals. It helps in understanding the distribution of data, making it easier to answer questions like "How many data points are below a certain value?" or "How many are above it?" This calculator supports both Less Than and Greater Than cumulative frequencies, offering flexibility for various analytical needs.
Types of Cumulative Frequency
- Less Than Cumulative Frequency: Represents the total frequency of all data points up to and including a specific value or class interval. For example, if you have test scores, it shows how many students scored at or below a certain mark.
- Greater Than Cumulative Frequency: Shows the total frequency of data points above a specific value or class interval. This is useful for understanding how many data points exceed a threshold, such as students scoring above a passing mark.
How to Use This Calculator
Follow these steps to calculate cumulative frequencies:
- Select the input type: "Raw Data" for a list of numbers (e.g., 1, 2, 2, 3) or "Frequency Table" for class intervals with frequencies (e.g., 0-10: 5, 10-20: 8).
- Choose the cumulative frequency type: "Less Than," "Greater Than," or "Both."
- Enter your data in the provided textarea, following the format shown in the placeholder.
- Click "Calculate" to view the results in a clear, tabular format.
This tool is designed for students, researchers, and data analysts who need quick and accurate cumulative frequency calculations. Whether you're analyzing survey results, exam scores, or other datasets, this calculator simplifies the process.
