q2 i? The control group's retention test mean (13.20) did not differ significantly from its post-test mean (13.03); equivalence was not tested. → Coşkun and Eker 2018

Evidence¶

Coşkun and Eker 2018¶

İsmail Coşkun, Cevat Eker. (2018). The Effect of Teaching Activities Done by Using Activity Based Posters on the Students' Academic Achievements, Retention Levels in Their Learning. Universal Journal of Educational Research 6(4): 585-597. https://doi.org/10.13189/ujer.2018.060402

q2 · i? · causal · r2

Paired t test comparing the control group's post-test (mean 13.03, SS = 4.00) with its retention test (mean 13.20, SS = 4.20), n = 30. Table 10 prints t = 0.17, p = 0.86, which is not significant, although the article's prose again labels the difference significant.

"The difference between retention test scores and academic achievement post -test scores of the control group was compared with the t test and it was found there was a significant difference with the value obtained (t=0,17) and [p<0.05]."
