Description

The data used in Chapter 7, Table 9

Usage

1

Format

An object of class data.frame with 36 rows and 3 columns.

Details

The following data is a generalization of the blood pressure data given in Table 7.5 (which itself was a generalization of the data given in Table 7.1). After the interaction is found to be significant, a common recommendation is to examine simple main effects. Recall that a simple main effect is the main effect of one factor given a fixed level of another factor. In this case interest is in determining if there are any differences in drugs (a) given biofeedback and (b) given no biofeedback.

Variables

score

blood pressure

feedback

the likelihood of there being a biofeedback or drug main effect

drug

the level of the drug factor

Synonym
