1. What is a Percentage Difference Calculator for 3 Values?

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.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{Avg Difference} = \frac{\sum \frac{|V1-V2|}{\frac{V1+V2}{2}}}{n} \times 100 \]

Where:

Explanation: For 3 values (A, B, C), it calculates percentage differences for pairs (A-B, A-C, B-C) and returns the average.

3. Importance of Percentage Difference

Details: Percentage difference provides a standardized way to compare values regardless of their magnitude, useful in scientific, financial, and statistical analysis.

4. Using the Calculator

Tips: Enter any three values (unitless) to compare. The calculator handles both positive and negative numbers.

5. Frequently Asked Questions (FAQ)

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.
