Absolute error is the difference between the experimental value and the actual value. Relative error, usually expressed as a percent, is the error relative to the correct value. For example,

ABSOLUTE ERROR:

We perform an analysis on a sample for Na. We find 34.0%. We turn in the results and the instructor tell us she made the samples and they were 36.0% Na. Absolute error is x

RELATIVE ERROR:

Same values as above.

relative error = [(34.0-36.0)/36.0]x100=5.56%
