Subclaims¶

q2 i2 A two-way mixed ANOVA on the entire SCI-ML instrument showed a significant interaction between time and intervention type, F(1, 76) = 4.86, p = 0.030, partial eta2 = 0.060. → Duane E. Wallace & Alec M. Bodzin 2017 q2 i? Pairwise t-tests showed post-survey scores significantly increased over pre-survey for the intervention group (t(38) = 2.38, p = 0.023) but not for the control group (t(38) = -0.80, p = 0.431). → Duane E. Wallace & Alec M. Bodzin 2017 (2)

q2 · i2 · causal · r2

Two-way mixed ANOVA on the entire SCI-ML instrument with group (control or intervention) as between-subjects factor and time (pre and post) as within-subjects factor, in a quasi-experiment with n=39 per group. The printed effect size for this interaction is partial eta2 = 0.060 (η² = 0.060), a medium-small effect.

"However, there was a significant interaction between the different time periods and the type of intervention that was used [F(1, 76) = 4.86, p = 0.030, partial eta2 = 0.060]."

q2 · i? · causal · r2

Follow-up pairwise t-tests on the entire SCI-ML instrument in the same quasi-experiment. The intervention group improved significantly while the control group did not; no effect size is printed for this pairwise contrast.

"Further analysis using pairwise t-tests revealed that the post-survey scores on the entire SCI- ML instrument significantly increased compared to the pre-survey scores for the intervention group (t(38) = 2.38, p = 0.023) but not for control group (t(38) = -0.80, p = 0.431)."
