Statistical Analyses of Data
A one-way analysis of variance (ANOVA) was used to determine if group
differences existed at pretest. Group means on all pretest measures were calculated.
Analyses of the one-way ANOVA disclosed that no significant differences between
groups existed on any pretest measure. Table 6 provides a summary of the one-way
ANOVA of group means at pretest.
