Box and Whisker Plots Introduction This leaﬂet will show how to calculate box and whisker plots. Box Plots are summary plots based on the median and interquartile range which contains 50% of the values. Whiskers extend from the box to the highest and lowest values, excluding outliers. A line across the box indicates the median. A box and whisker plot is a type of graphical display that can be used to summarise a set of data based on the five number summary of this data. The summary statistics used to create a box and whisker plot are the median of the data, the lower and upper quartiles (25% and 75%) and the minimum and maximum values. A box & whisker plot shows a "box" with left edge at Q 1 , right edge at Q 3 , the "middle" of the box at Q 2 (the median) and the maximum and minimum as "whiskers". Note that the plot divides the data into 4 equal parts. The left whisker represents the bottom 25 % of the data, the left half of the box represents the second 25 % , the right ... 5) Draw a box that begins at the lower quartile and ends at the upper quartile. 6) Draw whiskers from both ends of the box. The whiskers end at the extremes. How to Construct a Box and Whisker Plot Use the following data to make a box and whisker plot. 14, 21,19, 12, 13, 24, 26, 19, 15, 25, 19 Figure 1.
