Quick start
- Enter the numbers in your data set.
- Press Calculate summary.
- Read the mean, median, mode, and range.
- Check the sorted values when you want to verify the median or modes.
Best uses
Start here if one of these sounds like your job. The examples below show which inputs matter most.
- Find the average, median, most frequent value, and range quickly.
- Check small data sets for school, study, and everyday comparisons.
- See sorted data so the median and range are easy to verify.
- Copy the four headline statistics into notes or homework.
What each answer means
Mean is the total divided by the count. Median is the middle sorted value. Mode is the most repeated value. Range is maximum minus minimum.
The calculator keeps repeated modes when more than one value ties for most frequent.
When this tool is enough
Use this calculator for homework, quick checks, scores, small samples, and everyday data summaries.
Use the full Statistics Calculator when you also need quartiles, variance, or standard deviation.

FAQ in plain language
What is the mean?
The mean is the arithmetic average. Add all values, then divide by how many values there are.
What is the median?
The median is the middle value after the data is sorted. If there are two middle values, their average is the median.
What do the main Mean, Median, Mode, Range Calculator inputs mean?
The main inputs are the numbers, operation, mode, or known values the calculator needs. Keep units consistent, enter percentages the way the page label shows, and use the examples as a quick check before trusting the answer.
How should I read the Mean, Median, Mode, Range Calculator answer?
Read the headline answer, then check the supporting lines and examples to understand how the calculator got there. If one input changes, rerun the tool and compare the new answer instead of guessing.
What should I double-check before trusting the Mean, Median, Mode, Range Calculator?
Check units, signs, rounding, and the selected mode before copying the answer. If the number feels weird, rerun one of the examples first, then put your own values back in slowly.
What is the mode?
The mode is the most frequent value. A data set can have one mode, multiple modes, or no mode.
What is the range?
The range is the maximum value minus the minimum value.
