What is Percentage Difference?
Percentage difference is a measure of how much one value differs from another, expressed as a percentage of the average of the two values. It's commonly used in various fields such as statistics, finance, and science to compare two quantities or to track changes over time.
Formula for Percentage Difference
The formula to calculate percentage difference between two numbers n₁ and n₂ is:
\text{Percentage Difference} = \dfrac{|n_1 - n_2|}{\frac{n_1+n_2}{2}} \times 100 \%How to Calculate Percentage Difference Manually
- Find the Absolute Difference: Subtract the smaller number from the larger one and take the absolute value of the result.
- Find the Average: Add the two numbers together and divide by 2 to find the average.
- Calculate the Percentage Difference: Divide the absolute difference by the average, then multiply by 100 to get the percentage.
