The APA Publication Manual Sixth Edition includes expanded recommendations for statistical analysis and the reporting of research. Major themes include effect sizes, confidence intervals, power and precision, and meta-analysis. This is the second of two units on the new recommendations. It builds on the discussion of effect sizes and confidence intervals in the first unit. It discusses statistical power and precision, then introduces meta-analysis. It explains with examples how to follow the recommendations and how to interpret research reported in the new ways.
