Mathematical Models in Statistics

Mathematical Models in Statistics — Edexcel International A-Level Mathematics (Unit 8 / Statistics 1 (S1)). The opening topic of S1: what a statistical model is (a simplified mathematical description of a real-world population or process), and the four-stage modelling cycle (formulate → test → refine → use). Sets the framing for every later S1 topic — Normal, Binomial, regression, hypothesis tests are all examples of statistical models.
