About this worksheet

What students practice

  • Students identify the population and sample in project-progress investigations.
  • Students distinguish random selection from methods likely to produce biased samples.
  • Students explain why random samples support population conclusions without guaranteeing an exact match.

How to use

Use after introducing populations and samples. Have students evaluate each selection method, then discuss why sample size alone does not prevent bias.

Curriculum

Common Core standard covered

7.SP.A.1

Understand that a sample can tell about a population, and that random samples tend to represent the population well.
