chapter_7_table_11

The following data represents a two way factorial design where diagnosis
and task are fully crossed, each with three levels. Of interest for the 
results displayed in Table 7.12 is where the interaction contrast 
specified in Figures 7.3 and 7.4 is statistically significant. Namely 
the question pertains to whether the relationship of the mean of grammar
and classification versus recognition differs for those in the amnesic 
and Huntington's group.

The 'contrast' statement for the interaction (diagnose*task) effect 
essentially allows one to specify the necessary contrast coefficients 
as given in Figures 7.3 and 7.4. Note that the coefficients specified 
should be whole numbers.
