STAT210prob3.16: The Bioactivity of a Drug

Description

A pharmaceutical manufacturer wants to investigate the bioactivity of a new drug. A completely randomized single-factor experiment was conducted with three dosage levels. This data contains the obtained results of the experiment.

Usage

STAT210prob3.16

Format

A data frame with 12 observations (rows) and 3 variables (columns).

Column name Data type Description Values
[,1] Dosage character 3 different doses of the drug ("20g", "30g", "40g")
[,2] Activity integer The biological activity (24 - 52)
[,3] RESI1 numeric Residuals (-6.75 - 7.25)

Details

This is data from Exercise 3.16 in Design and Analysis of Experiments, 9th Edition, EMEA Edition.
