What is Percent Difference?
Percent difference is used to compare two values that represent the same type of quantity (e.g., the heights of two people) where neither is the 'original' or 'reference' value.

Use this when comparing two theoretical or experimental values where neither is 'correct'.
If you have a known/accepted value, use Percent Error instead.
The result is always positive if using the absolute difference.
