❓ Common questions
- What is the difference between percentage difference and percentage change?
- Percentage difference is used when both numbers have equal value and there is no original vs new value. Percentage change is used when there is a starting baseline (like an initial price rising or falling).
- Why do we divide by the average?
- Dividing by the average ensures that the result is symmetric. The difference between A and B is the same as between B and A.
