Biostatistics
Health data science
Biostatistics is the application of statistical methods to biological and health-related data.
The field underlies medical research, epidemiology, and public health—analyzing clinical trials, disease patterns, and population health trends.
Biostatisticians determine whether a drug's effects are real or due to chance, or whether a risk factor truly correlates with disease: The biostatistics showed the vaccine reduced infection rates by 40%.
