| Topic | Central limit theorem |
| Type | Sampling distribution theory |
| Difficulty | Moderate -0.5 This is a straightforward recall question worth only 3 marks, asking students to state a well-known theorem from their syllabus. It requires no calculation, problem-solving, or application—just reproduction of memorized content about the CLT (sample means approach normal distribution as n increases). While it's a Further Maths topic, the question itself is easier than average A-level questions that require multi-step work. |
