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.
