The formula to calculate the percentage accuracy (A) is:
\[ A = 100 - \left( \frac{Tv - Ov}{Tv} \times 100 \right) \]
Where:
Percentage accuracy is a measure of how close a measurement or test is to the true or theoretical value of that measurement or test. This is a ratio of the difference between true and measured divided by the true value.
Let's assume the following values:
Using the formula:
\[ A = 100 - \left( \frac{100 - 95}{100} \times 100 \right) = 100 - \left( \frac{5}{100} \times 100 \right) = 100 - 5 = 95 \]
The Percentage Accuracy ((A)) is 95%.
