Review Data interpretation and probability before starting →Ideas to recall
- Read titles, labels, scales, units, and sources before calculating.
- Percentage change compares the change with the original value.
- For equally likely outcomes, probability is favorable outcomes divided by total outcomes.
- Probabilities range from zero to one and complementary probabilities add to one.
Use these ideas to reason through each question; answer-specific explanations appear only after you check a response.
