Relative Accuracy Calculator

Formula

The formula to calculate the Relative Accuracy (RA) is:

\[ RA = \left| \frac{TV - AV}{TV} \right| \times 100 \]

Where:

Relative Accuracy: A measure of how close an approximate or measured value is to the true value, expressed as a percentage. It is often used in fields such as engineering, physics, and statistics to quantify the precision of measurements and calculations. A higher relative accuracy indicates a more precise approximation or measurement.

Let's say the true value (TV) is 100 and the approximate value (AV) is 95. Using the formula:

\[ RA = \left| \frac{100 - 95}{100} \right| \times 100 = 5\% \]

So, the relative accuracy (RA) is 5%.
