Type II errors … 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. l3 supergain
