A hypothesis is a statement of the predicted relationship between two or more variables
Allow theoretical propositions to be tested in the real world.
Guide the research design.
Dictate the type of statistical analysis for the data
Provide the reader with an understanding of the researchers expectations about the study before data collecting begins.
Source of Hypothesis-
From the researchers own experiences.
From previous research studies.
From theoretical propositions. This is the most important source of a hypothesis. This process of a hypothesis derivation involves deductive reasoning. A propositional statement is isolated from the study frame work and empirically tested.
Nursing research involves both inductive and deductive means of formulating hypothesis.
Hypothesis should always be written before the study and should not be changed after the study results are examined
