The objective of Statpedia is to allow everybody to easily grasp commonly used statistical concepts. You will not find here mathematical proofs or a scientific deep dive on each concept. Our objective is to explain in a simple way, to show how these concepts can be used in an actionable way, to explain when they should be used and to put each of them in perspective with the others. Links to scientific papers can be found in each article, for those who want to dig deeper.
