A statistician uses the scientific application of mathematical principles to the collection, analysis, and presentation of numerical data. Statisticians apply their mathematical and statistical knowledge to the design of surveys and experiments; the collection, processing, and analysis of data; and the interpretation of the experiment and survey results. Opinion polls, statements of accuracy on scales and other measuring devices, and information about average earnings in an occupation are all usually the work of statisticians.
The mathematics required for statisticians includes but is not limited to College Algebra, Trigonometry, Calculus I, II, and III, Linear Algebra, Ordinary Differential Equations, Theory of Analysis, and Mathematical Models.
