A research area cluster survey is a method used to gather information on a specific topic or theme by grouping related research areas together. Researchers use this survey method to assess the current state of knowledge, identify gaps in the research, and determine potential areas for future study. By organizing the survey into clusters, researchers can gain a comprehensive understanding of the topic and easily analyze the data collected. This approach helps to streamline the research process and guide future research efforts in a more targeted and efficient manner.
