Segmentation is a research area that involves dividing a target market into distinct groups based on specific characteristics or criteria, such as demographics, behavior, or needs. This process helps businesses or researchers better understand their audience and tailor their products, services, or strategies to meet the unique needs of each segment. Segmentation can lead to more effective marketing campaigns, improved customer satisfaction, and increased profitability. Researchers may use various methods such as clustering algorithms, regression analysis, or decision trees to identify and define segments within a population.
