Description

Appearance measure of paint

Format

A data frame with 32 observations on the following 6 variables.

a

a factor with levels H L

b

a factor with levels H L

c

a factor with levels H L

d

a factor with levels H L

e

a factor with levels H L

mw

a numeric vector

Details

These data are from a designed experiment to study the impact of 5 process factors on the molecular weight of a paint. The Mw is the response of interest as it in turn impacts quality characteristics of the paint. This study was run to better understand the influence of processing variables on the resulting Mw of the formulations.
