About All Statistics Formulas

Statistics are the results of data displayed in the form of tables to graphs. Statistics is widely applied in various disciplines, both natural sciences (eg astronomy and biology as well as social sciences (including sociology and psychology), as well as in the fields of business, economics, and industry.
