Which term refers to the concept that defines how close the results of multiple trials of something are to each other?

• A. Consistency
• B. Accuracy
• C. Precision
• D. Alignment

Answer: (C)

The term that defines how close the results of multiple trials are to each other is precision. Precision refers specifically to the reproducibility or repeatability of a set of measurements, illustrating how consistently the same values can be obtained under the same conditions. It does not concern itself with how close these values may be to the actual or true value; instead, it focuses on the scatter or distribution of the values obtained from repeated measurements. In contexts such as laboratory experiments, precision is critical because it indicates the reliability of the procedure being used. If a set of measurements yields very similar results each time, it is considered precise. Thus, a precise measurement will have little variation among repeated trials, demonstrating that the measuring process is standard and consistent.
