q2 · i? · causal · r1
Paired t-test on the 20-learner Input Enhancement group's 50-item vocabulary pretest and seen posttest after 24 sessions of selecting from textually highlighted words. The article reports t=33.03, df=19, and concludes the strategy "was effective in improving vocabulary knowledge of Iranian EFL learners".
"The comparison of the means on the pretest and posttest scores of Input Enhancement group indicated that there was a statistically difference (t=33.03, df=19, p=0. 000>0.05) between the perform ance of Input Enhancement group in pretest and achievement posttest"
