Statisticians may also work in education, engineering and in other non-science sectors such as business. Work is done primarily in an office setting, but they may also travel to sites to collect data to analyze later.
Statisticians may work for government or in the private sector. Statistician positions generally require a graduate degree in mathematics or statistics, but some jobs may only require a bachelor's degree.
