In ordinary usage, “accurate” and “precise” are often used as rough synonyms, but scientists like to distinguish between them. Accurate measurements reflect true values; but precise measurements are close to each other, even if all of them are wrong in the same way. The same distinction applies in scientific contexts to the related words “accuracy” and “precision.”

This distinction is not likely to come up outside of contexts where it is understood, but science writers might want to be aware that the general public will not understand this distinction unless it’s explained.
