Answer to Question 1

Accuracy refers to how well the experimental value agrees with the true or exact
value. Precision refers to the degree of reproducibility of a measurement, that is, to
the maximum possible variations in of the actual measurements taken. Both may be
expressed as a plus/minus correction value or as a percentage.

Answer to Question 2

Measurement is the comparison of an unknown quantity to a standard. Example: The

long as a standard centimeter.
