Biostatistics is a branch of statistics that applies statistical methods to analyze and interpret data related to health and biology. It plays a crucial role in designing studies, collecting data, and drawing conclusions about public health, medicine, and environmental science. By using biostatistical techniques, researchers can identify trends, evaluate treatments, and assess the effectiveness of interventions. In public health, biostatistics helps in understanding the distribution and determinants of health-related events in populations. It provides tools for analyzing data from clinical trials, epidemiological studies, and health surveys, enabling scientists and policymakers to make informed decisions that improve health outcomes and prevent diseases.
