Description

The data used in Chapter 7 for Table 5.

Usage

1
data("chapter_7_table_5")

Format

A data frame with 30 observations on the following 3 variables.

score

blood pressure

feedback

the likelihood of there being a biofeedback or drug main effect

drug

the level of the drug factor

Details

This table represents hypothetical data from a study investigating the effects of biofeedback and drug therapy on hypertension. We (arbitrarily) refer to the presence or absence of biofeedback as factor A and to the type of drug as factor B.

The following data is a generalization of the blood pressure data given in Table 7.1 (as there are now three, rather than two, levels of the drug factor). In addition to assessing the likelihood of there being a biofeedback or a drug main effect, the interaction is explicitly taken into consideration. The results replicate those given in Table 7.7.

Rather than making use of the One-Way ANOVA procedure, it is necessary to use a more general procedure, namely that of the Univariate procedure.
