Document Summary

Hypothesis is a declarative statement identifying the predicted relationship between two or more variables. The direction of the predicted relationship is also specified in this statement.

Variables of the study must lend themselves to observation, measurement, and analysis. A sound hypothesis is consistent with an existing body of theory and research findings. Readers should be able to identify the flow of ideas, from the research question to the literature review, to the theoretical framework, and to the hypothesizes. If criterion met, reader will understand the following: Statement should be worded in a clear, simple and concise terms. Research hypothesis (scientific hypothesis) consists of a statement about the expected relationship of the variables. Research hypothesis indicates what the outcome of the study is expected to be. Research hypothesis is also either directional or nondirectional.
