With sample size determination mastered, you're ready to explore effect sizes in depth. Effect sizes quantify the magnitude of effects in standardized units, making them comparable across studies and contexts. You'll learn:
- Why statistical significance is not the same as practical significance
- How to calculate and interpret various effect size measures
- The relationship between effect size, sample size, and significance
- How to report effect sizes alongside p-values for complete statistical reporting
After effect sizes, you'll learn about multiple comparisons: what happens to power and error rates when you conduct many tests simultaneously. The final section ties all these concepts together with practical guidelines for statistical analysis and reporting.
