key to reading box and whisker plots

Published 2018-04-23 at 216 × 432 in Visualizing Multi-Dimensional Data Sets.

Visual description of a box and whisker plot. The maximum and minimum are the "whiskers" of the plot. The other horizontal lines (1st quartile, median, 3rd quartile) divide the data into four parts. That is, 25% of the data occurs between the minimum and the 1st quartile, 25% occurs between the 1st quartile and the median, etc. The middle 50% of the data is the "box." The mean is depicted with a red diamond. Occasionally, outliers will be present. These will be represented as single points outside of the box and whisker plot.
