Q1 is represented by the far left hand side of the box. For this graph, the left whisker end is at approximately 0.75. The minimum is the far left hand side of the graph, at the tip of the left whisker. However, they can be a useful tool for getting a quick summary of data. Finally, the median is represented by a vertical bar in the center of the box.īox plots aren’t used that much in real life. The far left of the chart (at the end of the left “whisker”) is the minimum (the smallest number in the set) and the far right is the maximum (the largest number in the set). At the ends of the box, you” find the first quartile (the 25% mark) and the third quartile (the 75% mark). The main part of the chart (the “box”) shows where the middle portion of the data is: the interquartile range. The maximum (the largest number in the data set), shown at the far right of the box.Ī boxplot is a way to show a five number summary in a chart.Third quartile, Q 3, shown at the far right of the box (at the far left of the right whisker).The median is shown as a line in the center of the box.First quartile, Q 1, is the far left of the box (or the far right of the left whisker).The minimum is shown at the far left of the chart, at the end of the left “whisker.” The minimum (the smallest number in the data set).

Five pieces of information (the “ five number summary“) are generally included in the chart: The box and whiskers chart shows you how your data is spread out. Measures of center include the mean or average and median (the middle of a data set). Measures of spread include the interquartile range and the mean of the data set.

A boxplot, also called a box and whisker plot, is a way to show the spread and centers of a data set.
