H2 Maths Probability & Statistics | Free Notes
Free H2 Maths Probability & Statistics notes: key formulas, worked examples, and exam techniques for distributions, hypothesis testing, and regression.
Q: What does H2 Maths Statistics Notes: Probability and Statistics Overview cover?
A: Probability rules, binomial and normal models, sampling mean ideas, hypothesis tests for a population mean, and regression summarised for the 2026 H2 syllabus.
Before you dive in\ Reset your IP combinatorics and binomial knowledge so conditional probability and distribution work feel natural. Keep the GC set to Exam Mode and know wherebinompdf,binomcdf,normalcdf,invNorm, and regression features sit.
If you need one H2 Maths statistics page to revise before Paper 2, use this as the overview and then branch into the sub-topics below for targeted drills. For the full topic map, paper weightings, and official PDF link, see our H2 Maths Syllabus 2026-27 overview.
- Statistics turns data into decisions under uncertainty: Name the variable and context.
- Probability rules, distributions, tests, and regression each answer a different question: Identify the question type before using formulas.
- Paper 2 rewards interpretation as much as computation: End each answer with a plain-language statement.
Concrete example: "Find a probability" points to a distribution, while "is there evidence the mean changed?" points to hypothesis testing.
Status: SEAB's current H2 Mathematics (9758) syllabus PDF is labelled for 2026. Topic 6 is assessed in Paper 2 Section B (Probability and Statistics, 60 marks); Paper 1 is Pure Mathematics only.
Model-choice checkpoint
Before reaching for a calculator command, decide what kind of object the question is asking about. Most statistics errors start when a student uses the right formula family for the wrong question type.
| Question wording | First model choice | What to write before calculating | Common trap |
| "What is the probability that..." | Probability rule, binomial model, or normal model |
