Definition # 2
Statistics have two aspects that are theoretical and applied.
Applied statistics involves the use of formulas, theorems, and laws to solve real-world problems.
Mathematical or theoretical statistics is concerned with the development of formulas, theorems and laws. It also aims to prove that these formulas, theorems, and laws are actually correct.
Decisions made using statistical methods are known as educated guesswork. On the other hand, when a decision is made without using statistical methods, we call it pure guesswork. And of course, guesswork is often not reliable.
In this unit on statistics, you will mainly learn about applied statistics. The aim of the class is to help you think statistically and make educated guesses.
