Sequential Design

Sequential design is a research approach where data collection happens in stages, and each stage is informed by the results from the previous one. Instead of gathering all data at once, researchers analyze early results to decide the next steps—such as whether to continue, modify, or stop the study. This method allows for more flexible, efficient, and potentially quicker decision-making, as resources are focused on the most promising areas. It's commonly used in clinical trials and experiments to ensure safety, improve accuracy, and adapt to new information during the research process.
