Key examiner messages
Top priorities from the principal examiner before you revise
Many candidates struggled with the practical calculation questions.
For example, the Spearman's Rank Correlation test in Unit 2 and the Wilcoxon Signed Ranks test in Unit 4 required meticulous completion of differences and rankings.
Students who secured maximum marks here followed mathematical formulas carefully and presented their final values to the requested decimal places.
In contrast, marks were easily lost in the extended-response essays (12, 16, and 20 marks) due to a common candidate pitfall: writing purely descriptive (AO1) essays with minimal application (AO2) and evaluation (AO3).

Command word playbook
How to match each command word to the expected response style
Give reasons and link mechanism to outcome; each point needs a because/so chain.
Weigh arguments for and against with evidence; end with a supported judgement.
State features in sequence or list observable properties — do not explain causes unless asked.
Show formula, substitution, and unit; method marks need visible working.
Match the expected response style for “Assess” questions.
