EFL Reading Comprehension Post-Test Scores from a ChatGPT-Mediated Study

60 male preparatory-year students at a Saudi Arabian public university participated in a quasi-experimental study on reading comprehension. Post-test scores show a statistically significant difference between the ChatGPT-mediated mind mapping group and the control group, with a medium-to-large effect size. The dataset, shared by Naji Alyami, contains the Mann-Whitney U test results for these scores.

Use Cases

• Replicate statistical analysis of educational interventions based on reported test scores and p-values
• Compare effect sizes in language learning studies based on the reported r=0.52 value
• Design similar quasi-experimental studies in EFL contexts based on the described 10-week intervention structure

Strengths

• Includes a concrete statistical result (U=180.00, p<.001) from the study
• Effect size is quantified (r=0.52), allowing for meta-analysis
• Dataset is openly licensed under CC-BY-4.0 for reuse

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The 5.5 KB file size indicates a very limited scope, likely containing only summary statistics
