Introduction:

The percentage difference is a mathematical way to express the difference between two values relative to their average value. It's commonly used in statistics, finance, and other areas to compare changes between numbers.



Understanding Percentage Difference:



The percentage difference quantifies the difference between two numbers as a percentage of their average value.

It's different from percentage change, which compares the difference to the original number.

Formula for Calculating Percentage Difference:



The formula is: Percentage Difference = (Difference / Average of the two numbers) × 100%.

The difference is the absolute value of the subtraction of the two numbers.

Example:



If you have two numbers, 100 and 120:

First, find the difference: |120 - 100| = 20.

Find the average of the two numbers: (100 + 120) / 2 = 110.

Then calculate the percentage difference: (20 / 110) × 100% ≈ 18.18%.

Key Points to Remember:



The percentage difference is always a positive number.

It provides a way to compare the magnitude of the difference between two numbers relative to their scale.
