Three connected investigations

  1. 01Samples to Conclusions: Check the Frame Before the CountName the group a conclusion concerns, inspect who can enter the sample, and recognize clear coverage gaps.Open
  2. 02Samples to Conclusions: Expect Variation in a SampleCompute simple sample proportions, compare repeated samples, and treat variation as information rather than proof that one count is wrong.Open
  3. 03Samples to Conclusions: Report an Estimate Without OverclaimingTurn a sample count into an estimate, state the sample’s scope, and avoid claims that the observed data cannot support.Open

What this path asks you to reason about

  • Separate the target population from the reachable sampling frame.
  • Interpret different sample proportions as expected variability rather than automatic error.
  • Report an estimate with its scope and collection limits visible.
