A poster should communicate evidence, not decorate uncertainty
A student produces a colourful poster claiming a plant treatment doubled growth. The graph looks impressive but lacks units and sample size. The gold standard is a visual explanation that helps readers understand the investigation accurately.
Lead with the research question
Make the purpose easy to identify before presenting methods or conclusions.
Show the essential method
Explain the comparison, measurements and controls without overwhelming readers with procedural detail.
Choose truthful visuals
Axes, scales, labels and units should allow fair interpretation. Avoid exaggerated graphics.
Report results with context
Show relevant values and variation where appropriate rather than only a dramatic headline.
State limitations
A small sample or uncontrolled factor may restrict what can be concluded.
Design for readability
Clear hierarchy, appropriate contrast and concise explanations help readers navigate the evidence.
Break-test: the poster looks excellent but the claim is unsupported
Can the student revise the conclusion and preserve the visual clarity?
