To calculate the Percent Correct (PC):
\[ PC = \left( \frac{C}{Q} \right) \times 100 \]
Where:
Percent Correct is a measure used to determine the accuracy or success rate of a set of attempts. It is calculated by dividing the number of correct attempts by the total number of attempts, and then multiplying by 100 to get a percentage. This calculation is useful in various contexts, such as education, testing, and performance evaluation, to assess how well someone or something has performed.
Let's assume the following values:
Using the formula:
\[ PC = \left( \frac{45}{50} \right) \times 100 = 0.9 \times 100 = 90\% \]
The percent correct is 90%.
