Paste a list of numbers to get the mean, median, mode, range, and count — all at once. Numbers can be separated by commas, spaces, or new lines.
Formulas
- Mean (average): sum of all values ÷ count of values
- Median: the middle value when sorted (or the average of the two middle values, for an even-sized list)
- Mode: the most frequently occurring value(s) — a list with no repeated values has no mode
- Range: highest value − lowest value
Worked example for 2, 4, 4, 4, 5, 5, 7, 9: mean = 5, median = 4.5, mode = 4, range = 7.
FAQs
What if my data has more than one mode?
This calculator shows every value tied for the highest frequency — if two different values both appear most often, both are shown.
What happens if I paste text that isn’t a number?
Non-numeric entries are skipped automatically, so you can paste messy data without needing to clean it up first.
