Paste a list of numbers and get all three centres at once: the mean (sum ÷ count), the median (middle value when sorted), and the mode (most frequent). On 2, 4, 4, 4, 5, 5, 7 the mean is 4.4286, the median is 4, and the mode is 4 — agreement across all three means no outlier is dragging the average around.
Separate numbers with commas, spaces, or new lines — non-numeric entries are ignored. The diagnostic move is comparing mean against median: a mean far above the median flags high outliers (a few big values pulling the average up), which is exactly when the median describes the “typical” value better. With no repeats there is no mode, and several values can share it.
It does not compute spread (range, standard deviation), quartiles, charts, or distributions — central tendency only. For skewed data, report the median alongside the mean rather than the mean alone.
Central tendency only — no spread or distribution measures.
Then there is no mode, and the tool indicates that. A data set can also have more than one mode, which it will list.
The median when outliers skew the picture (incomes, house prices); the mean when every value should count equally and the data is roughly symmetric.
Commas, spaces, or new lines all work — non-numeric entries are ignored.
