q2 i? Pretest diagnostic scores were similar for both groups and the difference was not significant (t=-1.66, p>.05). → Cristian Velandia-Mesa 2017

Evidence¶

Cristian Velandia-Mesa 2017¶

Cristian Velandia-Mesa, Francisca-José Serrano-Pastor, María-José Martínez-Segura. (2017). Formative Research in Ubiquitous and Virtual Environments in Higher Education. Comunicar, 51, XXV. https://doi.org/10.3916/C51-2017-01

q2 · i? · causal · r2

Baseline comparison in the quasi-experiment with non-equivalent groups (pretest means xp=38.83, σ=7 versus xp=40.55, σ=7.25). The article reports no significant pretest difference; initial equivalence was not guaranteed because assignment was by enrollment.

"significant differences are not observed between the two groups prior to being exposed to both experimental situations (t=-1.66; p>.05)."
