STAT210example5.1: The Battery Design Experiment

Description

An engineer is designing a battery for use in a device that will be subjected to some extreme variations in temperature. The engineer tests battery designs with three different plate materials at three levels of temperatures to investigate how these parameters affects the effective battery life.

Usage

STAT210example5.1

Format

A data frame with 36 observations (rows) and 3 variables (columns).

	Column name	Data type	Description	Values
[,1]	Material_Type	factor	3 types of material plates	(1, 2, 3)
[,2]	Temperature	factor	3 levels of temperature in °F	(15, 70, 125)
[,3]	Effective_life	integer	Battery life in hours	(20 - 188)

Details

The data is from Example 5.1 in Design and Analysis of Experiments. 9th Edition, EMEA Edition.
