STAT210prob14.13: Yield Experiment

Description

This is results after a process engineer tested the yield of a product manufactured on three machines. Each machine can be operated at two power settings and has three stations on which the product is formed. The machines were tested at both power settings, and three observations on yield were taken from each station. The runs were made in random order.

Usage

STAT210prob14.13

Format

A data frame with 54 observations (rows) and 4 variables (columns).

	Column name	Data type	Description	Values
[,1]	Machine	factor	3 machines were tested	(1, 2, 3)
[,2]	Power	factor	2 levels of power settings	(1, 2)
[,3]	Station	factor	3 stations per machine	(1, 2, 3)
[,4]	Yield	numeric	Product yield from each station per run	(22.0 - 37.1)

Details

The data is from Exercise 14.13 in Design and Analysis of Experiments, 9th Edition, EMEA Edition. In the exercise all three factors are assumed fixed.
