Lesson 5 of 9
Supports, goes against, or says nothing
Show on a big screenThe claim: "Hot oil puffs a puri faster." Three records arrive, each one a written result. What does each one do?
Step 1 of 4
- Claim: hot oil puffs a puri faster.
- Monday: hot oil 8 s, cool oil 15 s. It supports the claim.
- Tuesday: the oil smoked. It says nothing about oil heat.
- Friday: hot oil 14 s, cool oil 9 s. It goes against the claim.
Monday supports it, Tuesday says nothing, Friday goes against it.
Records can support a claim. They cannot prove it for certain. The next test could still go against it.
To contradict is to say the opposite.
The rule
A record that fits a claim supports it. A record that contradicts it goes against it. One clear record against a claim weakens it. A record that does not touch the claim says nothing.
Sort six records. Drag each to the lane for what it does to the claim.
