Practice question · Put in order
Order the steps of conducting a meta-analysis.
- Define a precise research question.
- Systematically search for all relevant studies using pre-set criteria.
- Statistically combine the effect sizes into one pooled estimate.
- Extract each study's numerical result, such as its effect size.
- Interpret the overall, more precise combined estimate.
Hints
- You must gather and extract the studies' numbers before you can pool them.
- Question first, then search, then extract, then combine, then interpret.
Show the answer
- Define a precise research question.
- Systematically search for all relevant studies using pre-set criteria.
- Extract each study's numerical result, such as its effect size.
- Statistically combine the effect sizes into one pooled estimate.
- Interpret the overall, more precise combined estimate.
Why
Define the question, search comprehensively, extract each study's effect size, pool them statistically, and interpret the combined estimate. The systematic search up front is what prevents cherry-picking supportive studies.
