Question 1
Residual Error Benchmark Conditions FIGURE 5.9 Factor diagram for the intra- venous fluids data. For this particular exam- ple, the structural factor (drug manufactur- ers) corresponds to columns, and has three levels, Abbot, Cutter, and McGaw. Recognizing the factors is sometimes tricky. See, for example, S5.2: Fishers Iris data. Exercise Set C tor diagrams. 1/ Leafhopper survival data. If you have studied organic chemistry, you know that the word sugar reters not just to one chemical compound, but to a whole class of similar compounds. Sucrose, glucose, and fructose are three common ones. Glucose and fructose are simple sug ars, with six carbon atoms per molecule, and sucrose (ordinary cane sugar) is a twelve-carbon sugar. It is reasonable to suppose that the structure of a sugar molecule has something to do with its food value, and it was exactly that thinking which led to this experiment with potato leafhoppers. There were four diets to be compared: a control (2% agar), plus control with each of the three kinds of sugar. The experimenter prepared two dishes with each diet, divided his leafhop- pers into eight groups of equal size, and randomly assigned them to dishes. The response was the number of days until half the insects in a dish had died: control (2.3, 1.7), control with sucrose (3.6, 4.0), control with glucose (3.0, 2.8), and control with fructose (2.1, 2.3). Arrange the data in a rectangle and draw the factor diagram.
