How is percentage difference calculated?

Percentage difference is calculated by finding the absolute difference between two values, dividing by their average, then multiplying by 100. Formula: |V1 - V2| / ((V1 + V2) / 2) × 100.

What is the difference between percentage difference and percentage change?

Percentage difference treats both values equally and is symmetric (comparing 100 to 120 gives the same result as 120 to 100). Percentage change assumes one value is the "original" and the other is "new".

When should I use percentage difference?

Use percentage difference when comparing two values where neither is clearly the "starting point", such as comparing prices from two different stores, temperatures in two cities, or test scores from two students.
