Introductions. Biostatistics—a combination word derived from biology and statistics, is the application of statistics to a topic in biology. BIOS includes the design of biological experiments, especially in medicine and health sciences; the collection and analysis of data from those experiments; and the interpretation of the results. 

The study of statistics explores the collection, organization, analysis, and interpretation of numerical data. The concepts of statistics may be applied to a number of fields that include business, psychology, and agriculture. When the focus is on the biological and health sciences, we use the term biostatistics.
