Question

Quizplus · Accepted Answer

Meta-analysis is a statistical technique that combines the results of multiple studies to increase the overall statistical power and generate more reliable conclusions. It is commonly used in health sciences and psychology to evaluate the efficacy of interventions or to identify patterns in diverse research findings. The other options - B, C, and D - do not accurately describe this method. The natural clinical test (B) is not a commonly-used technique, and the term is not well-defined in the literature. The standard error of measurement (C) is a statistical index that represents the amount of error in a measurement relative to the true score, but it does not involve combining study results. Double-blind experimental analysis (D) is a research design that controls for bias by keeping both the participants and the researchers blinded to the intervention's condition, but it also does not involve combining studies.
