Question 1

What is absolute difference?

Accepted Answer

Absolute difference is simply B minus A. It keeps the original units (e.g., dollars, seconds).

Question 2

How do I compute relative (percent) change?

Accepted Answer

Percent change is ((B − A) / baseline) × 100, where the baseline can be A (old) or B (new) depending on your context.

Question 3

What if the baseline is 0?

Accepted Answer

Percent change is undefined when the baseline is 0. Use absolute difference instead or pick a different baseline.
