Why is percentage difference always positive?

Because it uses the absolute value of the difference (|V₁ - V₂|), measuring the magnitude of divergence rather than a directional increase or decrease.

Absolute Difference |V₁ - V₂|

Average of Values (V₁ + V₂)/2

27.5

Derivation Steps

Calculate absolute difference: |25 - 30| = 5

Calculate average: (25 + 30) ÷ 2 = 27.5

Divide difference by average and multiply by 100: (5 ÷ 27.5) × 100 = 18.1818%

Step-by-Step Examples

Comparing 25 and 30

Finding percentage difference between two measurements.

Inputs: Value 1: 25, Value 2: 30

Result: 18.1818%

Absolute diff = 5. Average = 27.5. (5 / 27.5) × 100 = 18.1818%.
