The topic of probability and Statistics is a lot more than just a series of abstract ideas that math students learn in order to solve a problem on an exam. Probability and Statistics is a language used in many walks of life, from science to politics and sociology.

What are variables?

Variables are things that we measure, control, or manipulate in research. They differ in many respects, most notably in the role they are given in our research and in the type of measures that can be applied to them.

Variables are key in scientific, geo-political and sociological studies.
