Descriptive models are tools used to summarize and explain data in a clear and understandable way. They help identify patterns and relationships within datasets, making it easier to interpret complex information. Common examples include statistical summaries, graphs, and charts, which visually represent data trends and distributions. These models do not predict future outcomes but provide insights into existing data. By using descriptive models, researchers and analysts can communicate findings effectively, aiding decision-making in various fields such as business, healthcare, and social sciences. They serve as a foundation for further analysis and exploration.
