Evidence¶

Komachali and Khodareza 2012¶

Maryam Eslahcar Komachali, Mohammadreza Khodareza. (2012). The Effect of Using Vocabulary Flash Card on Iranian Pre-University Students' Vocabulary Knowledge. International Education Studies, 5(3). https://doi.org/10.5539/ies.v5n3p134

q2 · i? · causal · r2

Independent-samples t-test comparing the posttest scores of the two randomly assigned groups of 25 female pre-university students after the eight-session treatment; the article reports t observed 9.679 exceeding the critical value 2.064, so "the experimental group performed significantly better in the posttest". No effect size is printed.

"In the Table 3, the t observed is 9.679 and t critical at our selected significance level of 0.05 for degree of freedom 24 is 2.064. In other words, as the results in the Table 3 show, the t observed exceeds the t -critical implying that the experimental group performed significantly better in the posttest."
