Statistics can be used to describe, summarize, and analyze these data. in other situations, data are not yet available; in such cases statistical theory can be used to design an appropriate experiment to generate data. the experiment chosen should depend on the use that one wants to make of the data. Statistics has 2 aspects which are: theoretical or mathematical statistics deals with the development, derivation and proof of statistical theorems, formula, rules and laws. Statistical methods deal with properties of groups or aggregates. in many applications the entity of primary interest is an actual, physical group (population) of objects. these objects may be animate (e.g., people or animals) or inanimate (e.g., farm ̄eld plots, trees, or days).
