| Abstract: | Graphs useful in exploratory data analysis for checking assumptions and evaluating treatment, sequence, and period effects in a linear model from a crossover design are discussed. In particular, a two-period, two-treatment crossover design of a food sensory study is used to illustrate the applications of these graphs. |
