⚖️ Part 3: Evaluating Data Sources
8. Sarah wants to know "What is the favourite ice cream flavour of students at her school?" She asks only her 3 best friends. What is wrong with this data collection plan?
Nothing is wrong
The sample size is too small
She should ask teachers instead
Ice cream flavours change too often
9. Look at this survey question: "Don't you think chocolate is the best ice cream flavour?" What makes this a poor survey question?
