📚 Exam Techniques and Marking Criteria for Pre-U CAIE Statistics | Pre-U CAIE统计：答题技巧与评分标准

Mastering exam technique is just as important as understanding statistical concepts for Pre-U CAIE Statistics. This article explains the marking criteria used by examiners and provides strategies to maximise your marks by presenting your knowledge effectively.

掌握考试技巧对于Pre-U CAIE统计学来说，与理解统计概念同等重要。本文解释考官使用的评分标准，并提供策略，通过有效展示知识来最大化你的分数。

1. Understanding the Mark Scheme | 理解评分方案

In Pre-U CAIE Statistics, marks are classified into method marks (M), accuracy marks (A), and independent marks (B). Understanding the difference is crucial. Method marks are awarded for a correct approach, even if numerical mistakes occur later. Accuracy marks require the final answer to be correct, usually following a correct method. Independent marks are given for statements, definitions, or correct use of a formula regardless of method.

在Pre-U CAIE统计学中，分数分为方法分(M)、准确分(A)和独立分(B)。理解它们的区别至关重要。方法分是针对正确解题思路而给出的，即使后续出现数字错误也能获得。准确分要求最终答案正确，通常基于正确的方法。独立分是对表述、定义或正确使用公式给出的，与方法无关。

A typical allocation: in a hypothesis test, stating the hypotheses earns B marks, calculating the test statistic earns M and A marks, and writing the conclusion in context earns B marks. Always demonstrate the method clearly — you can secure M marks even if the final answer is wrong.

典型的分配：在假设检验中，陈述假设可获得B分，计算检验统计量可获得M和A分，写出情境下的结论可获得B分。务必清晰地展示解题过程——这样即使最终答案错误，你也能确保获得方法分。
