T-test on post-test vocabulary scores for 123 female EFL students showed the experimental group (M=30.189) significantly outperformed the control group (M=25.235), with η²=0.149.

"significant differences between the control (M= 25.235, SD= 6.430) and experimental group (M= 30.189, SD=5.214), t ( 121 ) = 4.609, p = 0. 001, η2= 0.149 on the vocabulary test score, in favor of the experimental group."
