Interval Ratio Calculator

Formula

To calculate the Interval Ratio:

\[ IR = \frac{U - L}{U + L} \]

Where:

\(IR\) is the Interval Ratio
\(U\) is the Upper Bound
\(L\) is the Lower Bound

What is an Interval Ratio?

An interval ratio is a measure used to compare the difference between two values relative to their sum. It is often used in various fields such as finance, statistics, and engineering to understand the relative difference between two quantities. The interval ratio provides a normalized value that can be used to compare different sets of data on a common scale.

Example Calculation 1

Let's assume the following values:

Upper Bound (\(U\)) = 10
Lower Bound (\(L\)) = 4

Using the formula:

\[ IR = \frac{10 - 4}{10 + 4} = \frac{6}{14} = 0.4286 \]

The Interval Ratio is 0.4286.

Example Calculation 2

Let's assume the following values:

Upper Bound (\(U\)) = 20
Lower Bound (\(L\)) = 5

Using the formula:

\[ IR = \frac{20 - 5}{20 + 5} = \frac{15}{25} = 0.6000 \]

The Interval Ratio is 0.6000.
