• T-Test could not be performed because all students in SHINE attended tutoring.
• Spearman Correlation: Not significant
• Interpretation: No clear evidence that tutoring significantly improved final grades.
Improvement Trends
• Final grades were slightly lower than predicted grades on average(-0.42 difference).
• Some students improved, but there was no strong link between attendance and performance.
Comparison with Other Cohorts
• Unlike boys and girls, all SHINE students attended both sessions, making comparisons difficult.
• Compared to the girls ' group, where attendance had a strong positive effect, SHINE students didn ' t necessarily outperform their predictions.
• Compared to boys, SHINE students performed similarly, with a slight decline in final grades relative to predictions.
Sixteen students took part
Underachieving boys
There was an improvement in grades of 6 students( 38 %) There was no change in grades of 9 students( 56 %) There was a decline in grades of 1 student( 6 %) Inferential Statistics Final Grade T-Test T-Statistic:-0.69 P-Value: 0.501 Interpretation: Attendance did not have a statistically significant impact on final grades. Predicted Grade Change T-Test: T-Statistic: 1.40 P-Value: 0.259 Interpretation No significant difference in predicted grade changes based on attendance. Spearman Correlation( Attendance vs. Final Grade) Correlation Coefficient:-0.13
Interpretation: There is a weak negative correlation, meaning attendance was not strongly related to final grades.
Improvement Trends: Grades remained close to predictions with minor variations.
