- For
- Japanese Statistics Certification Level 2 learners
- Worth noticing
- The author describes himself as a salaried worker who struggled with conventional study materials, rather than a statistics professional.
Field notes
The course outline groups its material into five stages, starting with descriptive statistics and ending with applied methods. Chapter titles name topics including Fisher’s three principles, Bayesian probability, the central limit theorem, and p-values. The author says he began building the resource after struggling to find explanations that answered his questions about why formulas work; the homepage identifies the project as personal and not an official certification site.
