Description
The data used in Chapter 7, Table 9
Usage
data(chapter_7_table_9)
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
