Explain under what conditions you would use percentage error and when you would use percentage difference. Why would you sometimes use both?

Question 2

Answer to Question 1

Percent error is defined as the ratio of the absolute difference between the
experimental and the accepted values to the accepted value, expressed as a
percentage. Percent difference is defined as the ratio of the absolute difference
between the experimental values to an average of the experimental values, expressed
as a percentage. Percent error is a measure of accuracy while percent difference
relates to precision, so both can tell something valuable about how well an
experiment has been done.
