Evidence¶

Effat Heidari Sirmandi, Sedigheh Abbasnasab Sardareh. (2016). The Effect of BBC World Clips With and Without Subtitles on Intermediate EFL Learners' Vocabulary Development. Malaysian Online Journal of Educational Sciences. https://eric.ed.gov/?id=EJ1116325

q2 · i? · causal · r2

One-way ANOVA on posttest scores of the three groups (between groups df = 2, within groups df = 57, F = 84.161, Sig. .000); the article states "there is a statistically significant difference among all three groups". No effect size is printed.

"The analysis in Table 3 shows that the computed significance equals 0.00 which is less than the significance level set for the study (.05); in other words there is a statistically significant difference among all three groups."
