Null Hypotheses, Research Hypotheses, and Theories, • Null hypothesis rejected → research hypothesis supported, concerns the relationship between one independent and one dependent variable, concerns a relationship where two or more independent variables, or two or more dependent variables, or both, are being examined, concerns the action of two variables in conjunction with each other, (Ho) predicts that no relationship exists between variables, and it is subjected to statistical analysis, or alternative hypothesis (H1); states the expected relationship between variables, the researcher merely predicts that a relationship exists; the direction of the relationship is not presented, the researcher predicts the type of relationship that is expected; they have several advantages- they make the expectations clear, allow more precise testing of theoretical propositions, and allow the use of one-tailed statistical tests.
