STAT210prob3.22: Conductivity in TV Colour Picture Tubes

Description

A manufacturer of television sets is interested in the effect on tube conductivity of four different types of coating for colour picture tubes. A complete randomized experiment was conducted, and this data contains the conductivity data.

Usage

STAT210prob3.22

Format

A data frame with 16 observations (rows) and 3 variables (columns).

	Column name	Data type	Description	Values
[,1]	id	integer	The television ID	(1 - 16)
[,2]	Coating_Type	integer	4 types of coating	(1 - 4)
[,3]	Conductivity	integer	The photoconductivity	(127 - 152)
