thyroid.df

<p>Data from an experiment to asses the effect of a new drug on the weight of
the thyroid gland using 16 laboratory animals. The animals were randomly
assigned into either a control group, or a treatment group, and each animal
had its bodyweight recorded at the beginning of the experiment and its
thyroid weight measured at the end of the experiment.</p>

A set of functions used in teaching STATS 201/208 Data Analysis at
the University of Auckland. The functions are designed to make parts of R more
accessible to a large undergraduate population who are mostly not statistics
majors.
