c
conclusions which are consistent with survey responses. That is if you
form an hypothesis from the indicators it can consistently be confirmed by
survey . The indicator values used here were manually derived from lists of
computer data but, once proven, lend themselves to computer analysis on a
regular basis. The rectangular Venn diagram was adopted as a solution to
the puzzling problem of how to easily show accurate overlap of circles of
different sizes. It takes a little practice but they are easy to. use;
Interpretation of the various indicators was facilitated by the divergence
of patterns. Proposed interpretations could be confirmed by the changes of
the indicators with different use patterns, One could say, “if the relat
ionship changas in way X then the indicator will change in way Yll and
confirm the hypothesis with another pattern from the study. This use of
test and course usage data permits an objective, in depth analysis of the
training relationships that can usually be achieved only by extensive data
analysis and survey. While not eliminating all need for on site survey in
training e*;raluation it supports less and better focussed survey time.
