Specificity & Sensitivity EXPLAINED [+Examples]

The video tutorial explains the concepts of specificity and sensitivity in diagnostic tests. Specificity is the probability that a patient has a condition given a positive test result, while sensitivity is the probability that a patient does not have a condition given a negative test result. The video uses examples, such as ACL and PCL tears, to illustrate these concepts. It also provides a mnemonic, 'spin' and 'snout', to help remember when to use specificity and sensitivity. The tutorial concludes with real-world examples and questions to reinforce understanding.
