q3 i? A pre-test ANOVA found no significant differences among AT, AN and control groups (F = 1.555, df = 117, p = 0.216). → Gambari 2014

Evidence¶

Gambari 2014¶

Gambari, I. A., Ezenwa, V. I., & Anyanwu, R. C. (2014). Comparative Effects of Two Modes of Computer-Assisted Instructional Package on Solid Geometry Achievement. Contemporary Educational Technology, 5(2), 110-120. https://eric.ed.gov/?id=EJ1105561

q3 · i? · causal · r1

One-way ANOVA on pre-test scores of the 120 students across the three groups, reported in Table 1: F = 1.555, df = 117, p = 0.216, which the authors read as showing the students were comparable before the experiment.

"the F-value of 1.555 was not significant at the 0.05 level. This indicates that there are no statistically significant differences among the performance of students taught with Animation + on-screen Text (AT), Animation + Narration (AN) and control group"
