The result indicates a statistically significant difference between the two groups, with students using AI tools obtaining higher mean scores than those using traditional methods.
APA-Style Summary
An independent-samples t-test showed that students who used AI tools (M = 8.40, SD = 0.89) performed significantly better than those who used traditional writing methods (M = 7.10, SD = 1.02), t(28) = 3.72, p = .001, d = 1.36. This suggests a large effect of AI tool use on writing performance.
Peer Review Comment
Your calculations appear to be correct, and the APA-style reporting is mostly accurate. One suggestion would be to include a brief interpretation of Cohen’s d (for example, indicating that it represents a large effect size) to make the results easier to understand. Additionally, you may want to mention whether the assumptions of normality and equal variances were checked.
