Challenge Problems
Push your limits with challenges.
Question 1
A clinical test has a 90% sensitivity and 80% specificity. The disease prevalence is 5%. How would you compute the probability of actually having the disease after a positive test result?
💡 Hint: Ensure you factor in the specificity for false positives.
Question 2
In a machine learning context, if a certain algorithm predicts a class with 85% accuracy, and the class prevalence is 30%, what would be the posterior probability of the class given a positive prediction?
💡 Hint: Break down accuracy into its components to understand true positives vs. false positives.
