This tool calculates the median from your histogram data quickly and accurately.
How to Use the Median from Histogram Calculator
Enter the class intervals and corresponding frequencies data into the input fields. Ensure that both fields contain the same number of values, separated by commas.
How it calculates the median:
The calculator follows these steps:
- Validates the input data to make sure the number of intervals matches the number of frequencies and that all frequencies are valid numbers.
- Computes cumulative frequencies to find the median class where the cumulative frequency is greater than or equal to half of the total frequency.
- Applies the median formula to find the exact median value:
- L is the lower boundary of the median class.
- F is the frequency of the median class.
- C is the class width.
- CF is the cumulative frequency of all classes before the median class.
Limitations:
This calculator assumes that the class intervals are in a proper numerical format with a consistent class width. If the intervals vary significantly or are improperly formatted, the results may be inaccurate.
