Accuracy Calculator

Enter the number of true positives, true negatives, and total samples into the calculator to determine the accuracy of a test.

Accuracy Formula

The following formula is used to calculate the accuracy of a test.

A = ( TP + TN ) / S

  • Where A is the accuracy
  • TP is the true positives
  • TN is the true negatives
  • S is the total number of samples

FAQ

What is accuracy?

Accuracy is a measure of a tests ability to achieve the correct result. For example, if a certain test should yield a value of 10, but the actual results in a value of 9, the accuracy is 9/10 = .90 = 90%.

When is accuracy used?

Accuracy is most often used in the medical field when analyzing how correct a specific test is.


Example

How to calculate accuracy?

  1. First, determine the number of true positives.

    Add up the total number of true positives produced by the test.

  2. Next, determine the number of true negatives.

    Add up the total number of true negatives produced.

  3. Finally, calculate the accuracy.

    Calculate the accuracy by summing the true negatives and positives and then dividing by the total number of samples (total number of tests performed)
