STAT210prob2.34: Measurements with Different Calipers

Description

Callipers are measuring tools and one of the quickest and most accurate methods for dimensional measurements. There are however multiple factors that can affect the measuring accuracy. The diameter of a ball bearing was measured by 12 inspectors, each using two different kinds of callipers.

Usage

STAT210prob2.34

Format

A data frame with 12 observations (rows) and 2 variables (columns).

	Column name	Data type	Description	Values
[,1]	Caliper_1	numeric	The diameter in inches	(0.265 - 0.268)
[,2]	Caliper_2	numeric	The diameter in inches	(0.264 - 0.269)

Details

This is data from Exercise 2.34 in Design and Analysis of Experiments, 9th Edition, EMEA Edition.
