Example with Two Grouping Variables, No Replication

This example illustrates using the data entry table for repeated measures designs in a one-factor situation and for two-factor situations without replication.

Suppose you tested four cold medications on four people, with an interest in the degree of drowsiness introduced. Each subject is given each of the four drugs in random order. Drowsiness is measured for each drug. The data are the following:

	Drug 1	Drug 2	Drug 3	Drug 4
Subject A	112	128	90	79
Subject B	100	135	85	70
Subject C	90	120	92	64
Subject D	95	117	97	85
