Description

The rubber data frame has 10 rows and 3 columns.

Usage

data(rubber)

Format

This data frame contains the following columns:

piece
a numeric vector with the number of the test piece
untreated
a numeric vector with measured abrasion resistance for untreated half
treated
a numeric vector with measured abrasion resistance for treated half

Details

These data are from a paired comparison experiment to assess the effectiveness of a chemical treatment in increasing the abrasion resistance of rubber. A more detailed description of the experiment is given in the lecture notes.
