glycogen: Glycogen content in rat livers

In labstats: Data Sets for the Book "Experimental Design for Laboratory Biologists"

Description

An experiment measuring the glycogen content in rat livers that uses subsampling.

Format

A data frame with 36 rows and 4 variables:

Glycogen:

Glycogen content.

Treatment:

A numeric treatment group indicator (1, 2, 3).

Rat:

Rat identification number. The numbers are not unique; each treatment has a rat numbered 1 and 2, but these not the same rats (rats are nested under treatment).

Liver:

A numeric variable indicating the liver piece. Each liver was divided into three pieces.

Details

Six rats were randomised to three treatment conditions (two per condition). Their livers were divided into three pieces and two measurements were taken on each piece for 6 x 3 x 2 = 36 observations. The rats are the experimental units and there are two levels of subsampling.
