The formula to calculate the absolute change is:
\[ X = a - b \]
Where:
An absolute change is a measure of the exact numerical difference between two numbers, typically an initial and final value. These initial and final values are also often referred to as beginning and ending values.
Let's assume the following values:
Using the formula to calculate the absolute change:
\[ X = 150 - 100 = 50 \]
The absolute change is 50.
