Paste a list of numbers separated by commas or spaces and the tool returns the mean (average), the median (middle value), and the mode (most frequent). Seeing all three at once shows whether a few outliers are dragging the average around.
This covers central tendency only — it does not compute standard deviation, quartiles, or a full distribution. For skewed data, the median often describes the typical value better than the mean.
That is the promise behind every tool here. Files are read in your browser tab, processed there, and discarded when you close it — never uploaded to our servers.
