๐Mean, Median & Mode Calculator
Paste a data set and get all descriptive statistics plus a histogram, with step-by-step working.
Free Mean Median Mode Calculator
Need the mean, median, and mode of a data set fast? Paste your numbers into our free mean median mode calculator and get every measure of central tendency instantly โ no manual sorting or averaging required.
Beyond the basics, you'll see the range, sum, count, and both population and sample variance and standard deviation, all with the formulas and working shown step by step. A histogram visualizes how your data is distributed, so you can spot skew or clustering at a glance. Multimodal data sets are handled properly โ every tied mode is listed, and data sets with no repeated value are clearly marked as having no mode.
Whether you're checking homework, summarizing survey results, or analyzing a small research data set, this tool gives you accurate answers with full transparency into how they were calculated. No sign-up, no downloads, no limits. See the About page or the FAQ for more.
About the Mean, Median & Mode Calculator
Key features
Flexible input parsing
Accepts numbers separated by commas, spaces, or new lines โ paste straight from a spreadsheet.
Full descriptive statistics
Mean, median, mode, range, sum, count, min, max, and both variance/SD measures in one view.
Step-by-step derivation
Shows the exact substitution used to find the mean and median, including the sorted list.
Multimodal handling
Lists every tied mode, or clearly states "no mode" when all values are unique.
Histogram
An auto-binned bar chart visualizes the shape of your data's distribution.
Population vs sample
Both variance and standard deviation are computed and labeled distinctly.
Frequently Asked Questions
How do I use this calculator?
Paste or type your numbers separated by commas, spaces, or new lines, and the mean, median, mode, and more are calculated instantly.
What if my data set has more than one mode?
All tied modes are listed; if every value is unique, the tool states clearly that there is no mode.
Does it show the calculation steps?
Yes, the formulas and substitutions for mean and median are shown, including how the median is found for even- vs odd-sized data sets.
What's the difference between population and sample standard deviation?
Population SD divides by n and is used when your data is the entire group of interest; sample SD divides by nโ1 and is used when your data is a sample used to estimate a larger population.
Can I paste data from a spreadsheet?
Yes, comma-, space-, and newline-separated values are all accepted.
Does it handle decimals and negative numbers?
Yes, all real numbers are supported.
Is there a limit to how much data I can enter?
No practical limit; the tool is designed for small-to-medium data sets typical of homework or reports.
Is my data stored anywhere?
No, everything runs in your browser and nothing is uploaded or saved.
Does it show a chart?
Yes, a histogram visualizes the frequency distribution of your values.
Is it free?
Completely free, with no sign-up or limits.
