Visualization methods enhance our understanding of sample data and help us make comparisons across samples. Box plots are a simple but powerful graphing tool that can be used in place of histograms to ...

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 ...

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.

Figure 1: Data visualization with box plots. M.S. and J.W. conceived of the box plot tool, and M.S. developed the tool with input from all authors; J.W. implemented ...
