The B.S. program in Statistics and Data Science at Lehigh University provides a body of principles for designing the process of data collection, for summarizing and interpreting data, and for drawing valid conclusions from data. Mathematical principles, especially probability theory, underlie all statistical analyses. Statistics forms a fundamental tool in the natural and social sciences as well as business, medicine and other areas of research.

This program offers two tracks: a *standard track *and an *applied track*, as well as a concentration in Actuarial Science.

### Standard Track Requirements
