The box and whisker visualization offers a view of both the mean and median along with four quartiles to identify statistical outliers. This is part two of a three-part series about Bing's data ...

Learn how to calculate the interquartile range from a variety of different data types and draw and interpret box-and-whisker diagrams.

The notches, requested with the NOTCHES option, measure the significance of the difference between two medians. The medians of two box plots are significantly different at approximately the 0.05 level ...

The following example shows how to create a box plot with box-and-whisker plots whose widths vary proportionately with the group size. The following statements create a SAS data set named Times2 that ...

Examined here were the accuracy and bias of estimates of whisker length based on box, line, and midgap plots. For each type of graph, a different sample of undergraduates viewed 48 single-plot graphs.

This study investigated the effects of display characteristics on the bias of estimates of whisker length of two different types of box-and-whisker plots. To test the hypothesis that the bias means of ...
