Calculate Relative Accuracy (RA)



Formula

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

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

Where:

Example

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%.
