Broad research questions provide a beginning focus for the study and help to narrow the literature review to a manageable number of topics. The Broad question is reformulated into to focused questions after the literature review is conducted.
How does the literature review impact a qualitative study?
How does the literature review impact a quantitative study?
In quantitative, the research problem or a similar one may have been studied for some time and a considerable amount of related knowledge about it may have accumulated. Then a literature review may suggest what will be found after data are collected and analyzed. Then, it is possible to formulate one or more research hypotheses.
How are hypotheses stated?
Research hypotheses generally are stated in either the present or the future tense. In rare instances. such as in the case of historical research (Chapter 8). the past tense is used. They also are stated in the form of declarative sentences, never as questions. Because they are (tentative) answers to research questions. It is a predictor of what the researcher will find. It is a statement of a relationship between variables supported by stats in the lit review.
It generally takes the form of a statement of a relationship between or among certain variables. In research studies. that are primarily quantitative, data that have been collected are examined using statistical tests to determine whether support for research hypotheses was found.
The term demographic variable really is a generic term that is used most often by researchers to refer to those commonly measured variables that give researchers (and. when reported readers of research reports) a clearer understanding of the general characteristics of research participants.
1) Potential for Testing
4) Relevance to the Problem
5) Consistency of Conceptualization
Specificity requires that the words chosen to describe the variables in the research
hypothesis and the relationship believed to exist between them should suggest only one meaning to the reader of the hypothesis.Definition
Hypothesis – “ Relevance to the Problem” Please define
The variables within the hypothesis the dependent (outcome) and independent (predictor) variables, should be stated at approximately the same level of abstraction or concreteness.
