Hypothesis validity refers to the extent to which research results reflect theoretically derived predictions about the relations between or among constructs. The role of hypotheses in theory testing is discussed. Four threats to hypothesis validity are presented: (a) inconsequential research hypotheses, (b) ambiguous research hypotheses, (c) noncongruence of research hypotheses and statistical hypotheses, and (d) diffuse statistical hypotheses and tests.
