Survey lens

Separate the respondents’ answer from a claim about the whole population.

These are different ratios

Support divided by responses describes the respondents. Responses divided by population describes participation. Neither calculation establishes that the respondents are representative.

Use the fictional 30-of-40 example, then increase responses while keeping recruitment limited to one club. Explain why a larger number alone does not repair a selection problem.
