Which are the two values used to determine precision?

Question

Question 22 options:

a. experimental mean and individual measurements
b. experimental mean and true value

Answer 1

The two values used to determine precision are:

a. experimental mean and individual measurements

Precision refers to how close individual measurements are to each other, regardless of how close they are to the true value. The experimental mean (average) and the individual measurements help in assessing the consistency of the measurements.
