Stability of a drug stored in bottle or blister packaging.

Description

Data from an experiment where 300 mg tablets from several batches were stored in either high-density polyethylene bottle or blister packages. The stability of the drugs in terms of the percent of claimed amount was assayed at several time periods.

Usage

Format

A data frame with 300 observations and five variables:

assay:

assay result (percent of claim)

package:

packaging type (bottle or blister)

batch:

drug batch

months:

time in storage
