### Explanation

**Absolute Change:**
Absolute change refers to the simple difference between the initial and final values without any consideration of relative or proportional factors. For instance, if a tax rate increased from 19% to 27%, the absolute change is found by subtracting the initial value from the final value.

**Relative Change:**
Relative change helps in understanding how significant a change is in comparison to the original value. It's often expressed as a percentage. To calculate relative change, you divide the difference between the new and original values by the original value, and then multiply by 100 to get a percentage.
