Statistical issues


Statistical issues that could be discussed include

1. Type 2 errors;

2. tradeoffs that researchers may use to enhance power (see table 4.1, p. 134);

3. Type 1 errors resulting from the publication process of preferring to accept articles that have significant results (the file drawer problem discussed on p. 130);

4. effect size (help students understand Cohen's d using this tutorial), and

5. scale of measurement and choice of statistical analysis.
