The discipline of Biostatistics has contributed substantially to the development of health, medical and biological sciences and has emerged as an important tool for research. By applying various statistical methodologies a variety of easily applicable diagnosis, treatment and prognosis methods have been developed with scientific validity and many diseases and health conditions have been understood and dealt with appropriately. Statistical methodologies form the strength of any research study so as to make valid judgments and conclusions. Statistical design and analysis methods are very widely used in Clinical Trials, Pharmacology, Genetics, Biotechnology, Basic Sciences, Epidemiological studies, Demography, Quality Control of Medical & Biological equipments, Medical Diagnosis & Prognosis and Health Economics.

Its importance in Public Health administration in identifying causative factors of various diseases and identifying health priorities and proper allocation and utilization of the available budget appropriately and judiciously has also been well recognized now. There is an ever growing demand for this subject due to all these reasons.
