q2 · i? · causal · r2

Paired-sample t-test on the 25 experimental-group students' teacher-made technical vocabulary scores before and after thirteen weeks of task-based instruction. The article reports the mean increased from 18.52 (SD 5.347) to 24.00 (SD 2.693) and the paired t of -6.326 was significant at p < .05.

"the t-value with its 24 degrees of freedom (df) was -6.326. In fact, the observed (6.326) was more than t-critical (2.064), at 0.05 level of significance (p<.05). As a result, a significant difference was detected between learners’ mean scores in the pre-test and the post-test within the experimental group."
