Final answer:
Meta-analysis is a statistical method that synthesizes findings from multiple studies to show where management techniques are more or less effective. It is particularly valuable because it provides a broader and more reliable perspective on a research topic, aiding stakeholders in making evidenced-based decisions.
Step-by-step explanation:
According to the "What Really Works" box, the true statement about meta-analysis is that it shows the conditions under which management techniques may work better or worse in the real world. Meta-analysis is a statistical technique that evaluates the results of nearly all previous studies on a specific subject. This method is beneficial because it assesses the collective evidence of multiple studies, which can provide a more accurate and comprehensive understanding of a research topic. Understanding the accuracy and application of meta-analysis is crucial for managerial decision-making, as it can guide organizational stakeholders on what works under specific conditions.
Meta-analysis differs from a case study, which provides an in-depth analysis of a single event, situation, or individual, and often its results are not generalizable. Meta-analysis, however, aggregates findings from multiple studies, enhancing the reliability of the conclusions drawn and contributing to evidence-based practice in various fields, including business and management. By focusing on empirical evidence, meta-analysis contributes significantly to the understanding of complex phenomena and supports informed decision-making processes in organizations.
