A grouping problem was proposed to identify the groups in which principles
would be placed as seen by subjects.
This test was aimed to see if the subjects grouped principles
similar to the grouping done by the researchers, that is if the
subjects 'saw' the same relations as the researcher. The subjects were
asked to sort principles into sets of related principles. They were
given 3 sets of 15 principles. A free form sorting procedure was used,
which does not restrict the subjects to pre-defined categories. The
groups created were analyzed using a pooled similarity matrix which
was analyzed with regard to random grouping and compared
to the groups anticipated by the researchers.
