In this site I offer visitors a way of **learning statistics** by **doing statistics.** By this method, the student learns statistics step by step, incorporating knowledge and solving real word problems as she and he acquire new techniques.

To aid this process, I explain in detail fundamental statistical tests / techniques / theories, and present their objectives, advantages, key ideas, and how they were developed, using published scientific articles and their collected data. Often proofs of theorems and detailed explanations are offered in pop-up boxes, which can be skipped, if the proofs are known or not of great interest. To help the visitor focus on subjects relevant to a research question, I use keywords linked with articles that fully explain and elaborate them. All calculations, tests, graphs, and programming are performed with **R** and **RStudio**.
