Statistics may refer to a collection of methods that are used for collecting, organizing, analyzing, presenting, and interpreting data.

## Statistics has two aspects and these are theoretical and applied.

Applied statistics involves using formulas, theorems, and laws to solve real-world problems.

Mathematical or theoretical statistics deals with the development of formulas, theorems, and laws. Furthermore, the goal is to prove that these formulas, theorems, and laws are indeed correct.

Decisions made with the use of statistical methods are called educated guesses. On the other hand, when a decision is made without the use of statistical methods, we call this pure guesses. And of course pure guesses are often not reliable.
