Research reviews are comprehensive evaluations of existing studies on a specific topic. They summarize findings, highlight trends, and identify gaps in the current knowledge. By analyzing multiple research articles, these reviews help researchers and practitioners understand the broader context of a subject, making it easier to draw conclusions and inform future studies. These reviews can take various forms, such as systematic reviews or meta-analyses. A systematic review follows a structured methodology to gather and assess relevant studies, while a meta-analysis statistically combines results from different studies. Both types contribute significantly to fields like medicine, psychology, and education.
