Full Description
This exam emphasizes the statistical assumptions underlying the application of meta-analysis techniques. A thorough understanding of these assumptions is vital for ensuring the validity of analytic results.
Identifying and testing statistical assumptions is essential to avoid misleading conclusions in meta-analysis. Inaccurate assumptions can significantly distort the synthesis of evidence, thus impacting health-related decisions made based on these findings.
Candidates will be assessed on their ability to articulate different types of statistical assumptions, the testing of these assumptions, and the implications of assumption violations during verbal assessments.
Candidates should also be prepared to discuss real-world examples illustrating the consequences of assumption violations in meta-analyses.
Sample Questions
- Why is it essential to test the assumptions of normality in meta-analysis?
- What are the consequences of violating the independence assumption in meta-analytic studies?
