What does precision refer to in a scientific context?

In a scientific context, precision specifically refers to the consistency of repeated measurements, indicating how closely the results of individual measurements or trials cluster together. When results display high precision, it means that the values are very similar to one another, even if they may not necessarily be accurate or match a known standard.

For example, if multiple measurements of the same quantity yield results like 4.98 mL, 5.01 mL, and 4.99 mL, these measurements are precise because they are closely grouped. Therefore, option B effectively captures the essence of precision in scientific measurement.
