The increase ratio is a measure of the total increase relative to the initial value. It is calculated by dividing the total increase by the initial value.
The formula to calculate the increase ratio is:
\[ \text{IR} = \frac{\text{TI}}{\text{IV}} \]
Where:
Let's assume the following values:
Using the formula:
\[ \text{IR} = \frac{25}{50} = 0.5 \]
The increase ratio is 0.5.
