Health literacy basics: can you read the signal without the panic?
A general-information quiz on evidence, risk, prevention and the everyday science language that often appears in health coverage.
In health reporting, what does correlation mean?
Correlation can be useful, but it does not by itself prove cause and effect.
Why do health stories often mention sample size?
Larger and better-designed studies can offer stronger signals than tiny or poorly designed ones.
Which phrase is the most responsible reading of general health information online?
General health coverage cannot know an individual medical history, medication list or risk profile.
What does prevention usually mean in public-health language?
Prevention lowers risk; it does not promise perfect protection.
Why should headlines about a single new study be read carefully?
A study can add evidence without settling the question. The quality and wider evidence base matter.
What does peer review usually mean for a scientific paper?
Peer review is a quality filter, not a guarantee. Methods, data and later evidence still matter.
Why can relative risk sound more dramatic than absolute risk?
A large relative change can still be a small absolute change. Both figures help readers judge scale.
In general health coverage, why is sleep often treated as a basic factor?
Sleep is a broad health factor. General coverage can explain its role without giving personal medical advice.
What is the responsible use of an online symptom article?
General articles cannot know an individual case. Urgent or personal concerns need appropriate professional help.
What can a nutrition label help a reader compare?
Labels help compare products, though the useful reading depends on serving size and the wider diet context.
