Numbers (frequency counts) are typically used in the formula but percentages can be as well. How do you calculate percentage change? • ((after value – before value) / before value) * 100 = % change. Simply subtract the before value from the after value; then divide by the before value. Multiply the result by 100.

We will need to divide the absolute difference by the average of those two numbers and express it as a percentage. The calculation scheme is as follows: Find the absolute difference between two numbers: |20 - 30| = |-10| = 10.
