A Panel Study is a research method that involves collecting data from the same group of individuals, known as a panel, over a specific period. This approach allows researchers to observe changes and trends in behaviors, attitudes, or opinions over time. By repeatedly surveying the same participants, researchers can gain insights into how certain factors influence outcomes. Panel studies are commonly used in fields like sociology, psychology, and market research. They help in understanding long-term effects and causal relationships, making them valuable for policymakers and businesses. The data collected can inform decisions and strategies based on observed patterns within the panel group.
