Statistics

Paste a list and read it back. Quartiles use the median of each half with the middle value excluded, which is the method the A-level formula book assumes, and other conventions give different answers.

Data, separated by commas, spaces or new lines

Box from the lower to the upper quartile, line at the median, whiskers to the furthest point inside 1.5 times the interquartile range. Anything beyond that is drawn as a point, because that is what makes it an outlier.
