Nader Asadi Aidinlou & Alireza Moradinejad. (2016). Short-term and Long-term Retention of Vocabulary through Authentic Subtitled Videos. Advances in Language and Literary Studies. https://doi.org/10.7575/aiac.alls.v.7n.5p.14

q3 · i? · causal · r1

Independent t test comparing post-test scores of 18 control and 18 experimental advanced EFL learners after 8 weeks of instruction; control mean 15.78 vs experimental mean 13.67, mean difference 2.111. The article reports "the difference is statistically significant, t (34) = 3.276".

"It shows that the difference is statistically significant, t (34) = 3.276, at p < .05, 2 -tailed. However, it should be mentioned that it was the control group that had a better performance."
