Subclaims¶

q2 i? A one-way repeated measures ANOVA found a significant effect of time of testing (p = .001). → Zambo 1994 q2 i? The Time-of-test by Group interaction was significant (p = .006), with group defined by gender and test sequence. → Zambo 1994 (2)

Omnibus repeated measures ANOVA on the four gender-by-sequence groups (n=155); Table 2 prints Time SS=6.238, F=11.511, p=.001 and Time*Group F=4.259, p=.006. No effect size printed.

"A repeated measures Analysis of Variance found a significant effect for time of testing (P=.001) and a significant interaction effect of time of testing, test sequence, and gender (P=.006)."

The interaction is described as disordinal and strongest for females who received the formatted version after the unformatted; Figure 1 plots pre and post means by group. Pretest ANOVA among groups was non-significant (p = .375).

"These results do indicate a significant effect of Time-of-test by Group (p = .006). Figure 1 provides a graphic representation of the disordinal effect we found indicating a strong change for female students receiving the formatted version after the unformatted"
