Get the five numbers that summarize any data set for a box plot. Paste your values and the tool returns the minimum, first quartile, median, third quartile, and maximum, plus the interquartile range for convenience. The median splits the data in half, the quartiles split each half again, and the minimum and maximum mark the extremes, so together they describe both the center and the spread without assuming a normal shape. Quartiles here use linear interpolation, the same method spreadsheets apply, so results match tools you already trust. The five number summary is the backbone of a box and whisker plot and a quick way to spot skew and outliers before running heavier analysis. Results update as you type. Everything is computed locally in your browser, so your data never leaves your device.
