LET’S TRY ONE
A proposal claims a new crossing reduced the mean wait time. Which evidence most directly tests that claim?
Comparable wait-time measurements before and after.
The claim concerns a measured change in waiting time.
Learning steps & teaching tips
Distinguish measurable claims, value judgments and evidence relevant to an invented community proposal.
- Separate a reported fact from a preference or proposed goal.
- Name the measure needed for a testable claim.
- Check whether the evidence represents the people and conditions named.
Try it together
Write one measurable claim and one value judgment about an imaginary park. Propose evidence for the first and reasons for discussing the second.
Find exactly what the claim says before deciding which evidence could test it.
