For the occasional 1-sided tests, such as with a noninferiority study design (see below), the standard is to use Î± = .025, giving the same Î± value as on each side of a 2-sided test with overall Î± = 0.05. However, contrastive analysis certainly cannot predict these developmental errors. endstream
