Statistics is a branch of applied mathematics that involves the collection, description, analysis, and interpretation of data drawn from a sample of a larger population. Statistical sampling is used in medicine, finance, marketing, and many other fields to increase understanding and inform decision-making.
The mathematical theories behind statistics rely heavily on differential and integral calculus, linear algebra, and probability theory.
Statistics involves calculating mathematical probabilities based on data collected from a sample group.
The two major areas of statistics are descriptive and inferential.
The work of statisticians is used in virtually all scientific disciplines as well as in finance, medicine, the humanities, government, and manufacturing.
