The following statements use the flight delay data of Example 18.1 to illustrate how to create side-by-side box-and-whisker plots with notches: title 'Analysis of Airline Departure Delays'; title2 ...

Use box plots to illustrate the spread and differences of samples.

The Gaussian form chosen for the variogram in the "Getting Started" section is based on the consideration of the plots of the sample variogram. For the coal thickness data, the Gaussian form appears ...

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.
