Internships for those seeking a career in biostatistics train students in a variety of common responsibilities, like performing research, developing plans for studies, selecting sample sizes, reporting findings, and analyzing and reporting on other research. As a biostatistics intern, you work with a professional biostatistician as a mentor to learn how to study and record living organisms and related data, usually in tandem with further studies within your degree program. Internships typically last anywhere between a few weeks to a few months, and are valuable ways of garnering both on-the-job experience as well as professional contacts.
