WebNov 17, 2024 · In those cases, it’s still not a problem. If the null is always false to some degree, then you don’t need to worry about Type I errors because that deals with true nulls. Instead, you’re worrying about Type II errors (failing to reject a false null) because that is applicable to false nulls. An effect exists but the test is not catching it. WebIn most cases, Type 1 errors are seen as worse than Type 2 errors. This is because incorrectly rejecting the null hypothesis usually leads to more significant consequences.

WebOct 17, 2024 · 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 negatives”. Type 2 errors happen when you inaccurately assume that no winner has been declared between a control version and a variation although there actually is a winner.
