Mean, Median, Mode Calculator
Calculate the average (mean), the middle value (median), and the most frequent value (mode) for any data set.
A mean, median, and mode calculator finds the average, middle value, and most frequent value of any data set, along with the range, providing step-by-step explanations for each measure.
Examples
Small Data Set
Frequently Asked Questions
What if there is more than one mode?
Quick Tips
- •Use the median instead of the mean when your data has outliers that skew the average.
- •Double-check your inputs — a single mistyped value can shift the mean significantly.
- •Use the step-by-step breakdown to verify intermediate calculations.

How to Use This Calculator
Enter your numbers separated by commas or spaces. Click Calculate to get the mean, median, mode, and range, along with brief step-by-step explanations of how each value is found. Useful for homework or quick checks on a data set.
Understanding the Formula
Mean = Σx / n. Median = Middle value. Mode = Most frequent value.
Examples
Small Data Set
For 1, 2, 2, 3, 7: Mean is 3, Median is 2, Mode is 2.
Frequently Asked Questions
What if there is more than one mode?
A data set can have one mode (unimodal), two modes (bimodal), or multiple modes (multimodal). If all values appear equally, there is no mode.
Assumptions & Limitations
- Assumes exact input values — rounding errors in the inputs will propagate to the result.
- Limited to real numbers; complex number operations are not supported.
- If all values appear equally often, the data set is reported as having no mode.
