Quizplus · Accepted Answer

The number of significant figures used in a result is a measure of its precision, not its accuracy. It reflects the level of detail and reproducibility in the measurements taken. Systematic error refers to consistent errors in the measurement process, while determinate error refers to errors that can be corrected or adjusted for. Human error refers to errors introduced by the person conducting the measurements.
