How can we differentiate between Type I and Type II errors, and which degree of error is more acceptable in medical testing outcomes for rare diseases?

Answer 1

Mary Collins

Type I error, or false positive, occurs when a test incorrectly indicates the presence of a condition. Type II error, or false negative, occurs when a test fails to detect a condition. In medical testing for rare diseases, minimizing Type II errors is generally more acceptable, as missing a diagnosis can have more severe consequences than a false positive.
