STAT210example5.2: Impurity in Chemical Products

Description

The impurity present in a chemical product is affected by two factors: pressure and temperature. This data shows a factorial experiment with a single replicate.

Usage

STAT210example5.2

Format

A data frame with 15 observations (rows) and 3 variables (columns).

	Column name	Data type	Description	Values
[,1]	Temperature	factor	3 levels of temperature in °F	(100, 125, 150)
[,2]	Pressure	factor	5 levels of pressure	(25, 30, 35, 40, 45)
[,3]	Impurity	integer	The impurity of each product	(1 - 6)
