2. Inferential Statistics

· t(29) = -5.12 

· p < .001 

· Cohen’s d = 0.93 

3. Effect Size Interpretation

· d = 0.93 → large effect size 

· → The teaching method has a strong impact on students’ performance

4. APA-style Summary

· A paired samples t-test showed that students scored significantly higher on the post-test (M = 7.8, SD = 1.0) than on the pre-test (M = 6.5, SD = 1.2), t(29) = -5.12, p < .001, d = 0.93.

· This indicates a significant improvement after the intervention.
