Summary of Two-way ANOVA in SPSS (Part 5)

Summary of Main Ideas

Study Method Effect on exam scores:
A significant effect of study method on exam scores was observed, with an F-value of 5.51 and a p-value of 0.29, indicating statistical significance. The partial eta squared value was 0.22, suggesting a moderate effect size.
Comparison of Study Methods:
The average exam scores were higher for spaced studying (78.5) compared to cramming (73.4).
interaction effect:
A significant interaction effect between volume and study method on exam scores was identified, with an F-value of 4.50, a p-value of 0.47, and a partial eta squared of 0.18. The interaction effect suggests that the relationship between study method and exam scores varies depending on the volume of music played during study sessions.
Visualization of interaction effect:
A plot was used to illustrate the interaction effect, showing non-parallel lines which indicate a significant interaction. The four conditions in the study were:
- cramming with no music
- cramming with high volume
- spaced studying with high volume
- spaced studying with no music
The best performance was observed in the spaced studying condition with no music, indicating that this combination led to higher exam scores compared to other conditions.
Conclusion:
The video concludes with a note that further analysis of the interaction effect will be covered in future videos.
