Statistics is a branch of applied mathematics specifically in the area of statistical theory which uses probability theory in the mathematical models.

Statistics form a key basis tool in business and manufacturing as well. It is used to understand measurement systems variability, control processes (as in statistical process control or SPC), for summarizing data, and to make data-driven decisions. In these roles it is a key tool, and perhaps the only reliable tool.
