Remember in school when the math teacher gave you a problem to solve, and how you felt when your answer matched the one in the back of the textbook? Didn’t it feel great knowing you solved the problem correctly?

Validating the answer to grade school math problems carries the same concept as validating analytical methods. When scientists validate an analytical method, they need to show that it correctly measures the metric they’re testing for. To effectively do so, first they need to identify a product with existing results for the test they’re running as a control. Then, once the results from the test come in, they can verify that their results match the known answer, just like in school when you could check if your answer matched the one in the back of the textbook.
