| Topic | Chi-squared test of independence |
| Type | Standard 2×3 contingency table |
| Difficulty | Moderate -0.5 This appears to be a blank answer page template from an OCR S2 exam paper. Without the actual question content visible, I cannot assess the difficulty. However, chi-squared tests of independence in S2 are typically standard procedural questions involving calculating expected frequencies, computing the test statistic, and comparing to critical values - making them slightly easier than average A-level questions. |
