Using data subsets in epidemiological studies offers several advantages: 1. Enhanced Precision: Subsets allow researchers to focus on specific groups, leading to more accurate and relevant findings. 2. Identification of Trends: Subsets can reveal trends and patterns that might be concealed in aggregated data. 3. Targeted Interventions: By understanding specific subsets, public health interventions can be better tailored to meet the needs of particular populations.
