Evaluating Statistical Reports · Part 2 of 3
3 exam-style questions with model answers, plus 3 quick multi-choice questions — every question on this part of the standard, grouped by the 1 page of notes they come from.
Write a full answer before you reveal the model one. That comparison is where the learning happens.
A survey reports 60% support, margin of error ±4%. Between which two values is the true level of support likely to lie?
Option X polls 52% and option Y 48%, margin of error ±3%. Explain whether the report can claim X is more popular.
A report claims a party 'surged' from 40% (±3%) last month to 44% (±3%) this month. Evaluate the claim and explain what would make a change convincing.
