Percentage Difference Formula:
From: | To: |
Definition: This calculator computes the average percentage difference between all pairs of three given values.
Purpose: It helps compare multiple measurements or values to understand their relative differences in percentage terms.
The calculator uses the formula:
Where:
Explanation: For 3 values (A, B, C), it calculates percentage differences for pairs (A-B, A-C, B-C) and returns the average.
Details: Percentage difference provides a standardized way to compare values regardless of their magnitude, useful in scientific, financial, and statistical analysis.
Tips: Enter any three values (unitless) to compare. The calculator handles both positive and negative numbers.
Q1: How is this different from percentage change?
A: Percentage difference compares any two values symmetrically, while percentage change measures increase/decrease from an original value.
Q2: Why average the pairwise differences?
A: Averaging gives an overall measure of variability among all values, not just between two extremes.
Q3: What does a 0% result mean?
A: It means all three values are identical (no differences between any pairs).
Q4: Can I use this with negative values?
A: Yes, the calculator works with both positive and negative values.
Q5: When would this calculation be useful?
A: Useful for comparing experimental results, financial metrics, test scores, or any set of three comparable values.
