S ome examples of these graph types are described below. Box Plot B ox plots display the median value, range, and upper and lower quartiles to show distributions in one or more subgroups. CrossGraphs box plots can also show individual outliers, and confidence intervals. Delta Graph D elta graphs show changes in value for a set of subjects. The endpoints of each line indicate the start and end values for one subject.
Different colors show subjects whose value increased, decreased or stayed the same.
The height of each bar can show counts, weighted counts, mean values, or distributions of a variable across subgroups. C rossGraphs histograms show distributions of continuous variables or statistics for discrete variables. CrossGraphs can overlay a fitted normal curve, and display error bars to show the standard error of measurement. Picket Fence T he height of each picket or symbol shows the value of a continuous variable for each subject. The pickets are sorted to show the variable's distribution.
