Table 3 shows the post-test achievement mean
scores of the experimental and the control group. The
results indicate that the mean score for experimental
group was 56.18 and that of control group was 50.18.
The results also indicate that the difference between
the achievement mean scores for experimental and
control groups t(80) = 0.031 is significant at the alpha
level of 0.05.
As shown in Table 4, the results indicate that the
mean score for experimental group was 41.41 with a
standard deviation of 6.82 and that of control group was
40.50 with a standard deviation of 7.19. The results also
indicate that the difference between the attitude mean
scores for experimental and control groups t(80) = 0.559
is not significant at the alpha level of 0.05. This,
therefore, means that the experimental and control
groups were at the same level of attitude at the start of
the study.
Table 5 shows the post-test attitude mean scores
of the experimental and the control group. The results
indicate that the mean score for experimental group
was 48.02 and that of control group was 41.68. The
results also indicate that the difference between the
attitude mean scores for experimental and control
groups t(80) = 0.000 is significant at the alpha level of
0.05.
