\code{M1} 
\code{M2} 

\item[Team] an ordered factor with levels
\code{T1S} < \code{T3S} < \code{T2S} < \code{T1A} <
\code{T2A} < \code{T3A} < \code{T1H} < \code{T3H} <
\code{T2H}

\item[Physique] an ordered factor with levels

}
\end{Format}
\begin{Details}\relax
Hicks (p.180, 1993) reports data from an experiment on
methods for firing naval guns. Gunners of three different physiques
(slight, average, and heavy) tested two firing methods. Both methods
were tested twice by each of nine teams of three gunners with
identical physique. The response was the number of rounds fired per
minute.
