Student objectives
- Decide whether a sample is likely to represent a whole population fairly.
- Spot sources of bias in how data is collected, like who was asked or how people were chosen.
- Explain why random sampling usually gives more reliable information than picking people conveniently.
- Use information from a sample to make a reasonable guess about what might be true for the full population.
Everyday practice
- Judging whether an online poll reflects what most people think or just the people who chose to vote.
- Deciding if a product’s reviews seem reliable when only a small group of customers left ratings.
- Noticing bias when a class survey only asks one friend group or one grade level.
- Using a few friends’ opinions to guess what snack might be popular at a party, and recognizing why that guess could be off.
