What must scientists do to ensure their results are trustworthy?

• A. Publish results.
• B. Rely on assumptions.
• C. Use statistical analysis to validate results.
• D. Collect accurate data and repeat experiments multiple times.

Answer: (D)

Trustworthy results come from collecting accurate data and repeating experiments multiple times. When data are precise and reproducible, you can see whether outcomes stay consistent across different trials and setups, which helps separate real effects from random noise. Repeated testing also lets you estimate variability and uncertainty, so conclusions aren’t based on a single, potentially lucky outcome. Publishing results is important for transparency, but it doesn’t by itself prove correctness if the data or methods were flawed. Relying on assumptions without evidence is risky, because untested premises can lead you astray. Statistical analysis is a valuable tool for assessing significance and confidence, but it depends on high-quality data and replicated experiments; statistics won’t salvage conclusions built on poor data or unverified methods.
