What is a Type 2 error also known as?


Understanding Type II Errors In the same way that type 1 errors are commonly referred to as “false positives”, type 2 errors are referred to as “false negativesfalse negativesA false negative error, or false negative, is a test result which wrongly indicates that a condition does not hold. For example, when a pregnancy test indicates a woman is not pregnant, but she is, or when a person guilty of a crime is acquitted, these are false negatives.https://en.wikipedia.org › False_positives_and_false_negativesFalse positives and false negatives – Wikipedia”.

Thus, a type I error is equivalent to a false positive, and a type II error is equivalent to a false negative.

Is a Type 2 error a random error?

A Type II error occurs when there really is a difference (association, correlation) overall, but random sampling caused your data to not show a statistically significant difference.
