Separate values with commas, spaces, semicolons or new lines — decimals, negatives and scientific notation welcome.
Three averages, four small steps.
The calculator does the statistics — you just feed it numbers. Here is the whole workflow.
Paste your numbers
Type or paste any list into the input box. Commas, spaces, semicolons, tabs and line breaks all work as separators — decimals, negatives and scientific notation (like 6.02e23) are fair game too.
Tune the options
Pick how many decimal places you want, and toggle the step-by-step working, sorted data, frequency table and extended statistics on or off. Every change re-calculates instantly.
Hit Calculate
Mean, median and mode land in the three headline cards; the full workings — sums, sorted order, frequencies, quartiles — sit right below them. Ctrl + Enter works too.
Copy & go
One tap on Copy results puts a plain-text summary on your clipboard, ready for your notes, homework or report. Nothing is stored anywhere.
Mean vs median vs mode — which one when?
All three are "averages" — measures of central tendency — but they answer different questions about your data.
The balance point
x̄ = Σx ÷ n
Add everything up, divide by the count. It uses every value, so it is the go-to for symmetric data — test scores, measurements, totals.
One outlier can drag it far off.
The middle ground
Med = middle of sorted x
Sort the values and take the one in the middle — half the data sits below it, half above. Immune to outliers, perfect for skewed data like incomes or house prices.
Ignores how extreme the values are.
The crowd favourite
Mo = most frequent x
The value that shows up most often. The only average that works for categories — shirt sizes, brands, survey answers — and for "what's typical" questions.
Might not exist, or might be several.
The mean is 22, but the median is 3. One wild value pulled the mean nineteen points above the median — which is exactly why salary reports and house-price news quote the median.
Frequently asked questions
The quick answers, without the statistics lecture — for the lecture, see the crash course above.
How do I find the mean of a set of numbers?
4, 8, 15 is (4 + 8 + 15) ÷ 3 = 27 ÷ 3 = 9. The calculator shows this full working in its Mean steps section.How is the median found when there is an even number of values?
4, 8, 15, 16 the middle pair is 8 and 15, so the median is (8 + 15) ÷ 2 = 11.5. With an odd count, the median is simply the single middle value.What is the mode if no value repeats?
Can a data set have more than one mode?
2, 2, 3, 3, 8 has two modes: 2 and 3.Which should I use — mean, median or mode?
Does the calculator handle decimals and negative numbers?
6.02e23. Separate them with commas, spaces, semicolons or line breaks — anything that cannot be read as a number is flagged and skipped.
