Scope of expertise

The publication explains introductory and intermediate statistical reasoning using documented models. This record establishes authorship and editorial accountability for work on this site; it does not claim ownership of a registered company, a degree, professional license, institutional appointment, or independent technical certification. Count & Chance does not represent its byline as a licensed medical, legal, financial, or engineering professional. Sources support definitions and methodological boundaries; they do not transfer authority to unrelated claims.
