For the hypothetical data contained in Table 13.2, eight participants were measured at three occasions. The question of interest is: “Is there a population mean difference between across Time 1, Time 2, and Time 3 measurement occasions?”

The analysis of the data proceed in exactly the same way as it did for the data given in Chapter 13 Table 1 (as well as it did for the repeated measures given in Chapter 11). For this reason step-by-step instructions are not given for this data set.
