*ro establish that the three groups were equivalent in ability, a
one-way analysis of variance ~3s conducted on the means of the students’
XFQTs, final grades from the resident Fire Protection Specialist Course,
and their CDC pre-test scores. Table 2 summarizes the one-say analysis
of variance on each factor among the three groups.

As cnr. be seen, the F ratios for each of these three student variables
were all non-significant, thus indicating comparable groups.
In order to test the cffcctivcncss of the instructional methods, a
one-k:3y annlysis of variance ws conducrcd on,thc zeans of the post-test
CLN: (final grxic) scores achieved by the three groups. Table 3 presents
this analysis of variance.

Inspection of ‘I’ablc 3 shoxs that the post-test score F ratio was 4.966;
this is a significan? vnluc indicating the post-test performance of the
?hree groups was not comparable.
To compare the differences of the three groups on the post-test
pcrformanse factof, a Series of t tests were run. Their results are
sumarized in Table 4.
