According to Cancer Researcher Andrew Vickers, statistics involves “turning data into knowledge.” Statisticians use math to help them gather, understand, and explain data (huge groups of numbers) about all sorts of different topics, from how well a soccer team or a baseball player did last season to how well a surgeon helps patients recover from an illness.  The “bio” in biostatistics refers to life.  Biostatisticians like Andrew Vickers work with data related to living beings.
