Line graphs are favored in epidemiology for several reasons:
1. Trend Analysis: They help in identifying trends and patterns over time, which is essential for understanding the epidemiology of infectious diseases. 2. Comparative Studies: They allow for the comparison of multiple datasets, such as the effect of different interventions or the progress of outbreaks in different regions. 3. Forecasting: They assist in predicting future trends based on historical data, which is crucial for public health planning and resource allocation.
