Biostatistics is the application of mathematical and statistical concepts to biological research, usually biomedical research. Classical methods of experimental design, inference, analysis of variance, regression, and survival analysis are among the areas to be mastered. Biostatistics has grown rapidly since 1950 and continues to be one of the fastest growing specialties of statistics.

Typically, biostatisticians are involved in four major areas of research: Laboratory research studies (e.g., examining disease processes, pharmacological effects of new drugs, genomic based studies of disease), Epidemiological studies (e.g., identifying factors that increase disease risk), Clinical trials (e.g., evaluating new drugs, procedures, or other treatment modalities in a rigorous manner to test for benefit or possible harm), Statistical research (e.g., developing new theory and techniques for current and emerging biomedical problems.
