Meta-Analysis Methods (psychbull-meta-analysis-methods)

This is the quantitative core of a Psychological Bulletin meta-analysis: turning coded study statistics into effect sizes, pooling them under a defensible model, and characterizing heterogeneity honestly. Psychological Bulletin expects MARS-compliant methods. This skill covers estimation; moderators and publication-bias diagnostics live in psychbull-moderators-and-bias.

When to trigger

• Computing effect sizes from coded statistics
• Choosing fixed-effect vs. random-effects (vs. multilevel) models
• Handling multiple effect sizes per study (dependency)
• Quantifying and interpreting heterogeneity
