Compare evidence with the claim it supports

Supplied materials

• Paper or a text document; all cases below are original fictional learning inputs.
• An adult may read aloud; drawing or spoken answers are valid. No personal health information or physical performance is required.
• The supplied fictional study records whether twenty adult volunteers could locate a general-information page. Eighteen succeeded. It supports a statement about that task in that sample. It does not show that the page cured illness, that children would have the same result or that all adults can use it. The claim-evidence table keeps task, sample and outcome distinct before drawing a conclusion.
• A fictional adult sample completes a page-finding task; the claim describes only that sample and task. What fits?
• The same adult-only study is used to claim identical child results. What fits?
• A navigation study is described as proof of curing illness. What fits?
• One anonymous story is used as a typical-result estimate for everyone. What fits?
• A sample finding is reported with sample size and the exact navigation task. What fits?
• A study counts button clicks but claims improved disease treatment. What fits?

Learn the idea

A health claim needs evidence that matches its population, intervention and outcome. A study of adults cannot automatically establish the same result in children. A testimonial may describe one experience but cannot establish a typical effect or cause.

Create a claim-evidence table. Mark what was measured, in whom and under what conditions. The strongest warranted conclusion stays within those facts. Even a well-supported general finding does not replace qualified interpretation for personal health decisions.

Use fictional study cards, not actual medical data. No personal trial or treatment choice is required. The task is reasoning about evidence limits; invented classroom results must not be advertised as clinical research or LifeStarter outcomes.

1. Mark the facts or constraints in the supplied case.
2. Apply the method explained above; draw a sequence, table or decision map.
3. Compare your result with the worked solution and explain the difference.
4. Complete the new cases, then check the changed-case extension.

Write a warranted conclusion for a fictional 12 person adolescent sample where 9 find a source page. Expected:9/12 in that supplied sample/task; no clinical effect, all-teen or actual platform-outcome claim.
