Understanding Percent Difference

Percent difference measures the relative change between two values, expressed as a percentage of their average. This makes it particularly useful for comparing values that are different but related.

The Formula

Percent Difference = |V₁ - V₂| / ((V₁ + V₂) / 2) × 100

Common Applications

  • Scientific measurements and experimental data analysis
  • Financial performance comparisons
  • Statistical analysis and data validation
  • Quality control in manufacturing

Tips for Accurate Calculations

  • Always use consistent units when comparing values
  • Consider the context when interpreting results
  • Be aware that percent difference is always positive
  • Use percent change instead if you need to show direction of change
