Methods of seeking knowledge of the following common characteristics
question
The first step for the nurse is to access the problem, for the researcher it is recognize the general problem area. The next step for the practicing nurse is to making a nursing diagnosis, and defining the specific problem is the second step in the research process. The clinical nurse then proceeds with planning and intervention whereas the researcher proposes hypotheses, tests them through experimental and nonexperimental approaches and manages data. In the final step the clinician evaluates outcomes; the researcher analyzes the data collected and disseminates the findings in relation to the patterns uncovered.

question
Is the process of selecting published materials that have relevance to the potential research. Doing such a review helps the researcher find out what is already known about the subject and prevents duplication of effort if the subject is already well studied. In addition, it helps illuminate what gaps in knowledge exist in the subject area and can point the way for new research directions.

Is a set of interrelated constructs or propositions that attempt to present or explain some phenomenon systematically.
answer
Theory
question
systematically the logical relationship between variables. Each nursing model depends on the individual researchers philosophy of human behavior and how that philosophy meshes with other ways of looking at science.
answer
The nursing model or theory should be a guide to identify and study
question
Is a key step in the research process identifies the direction that a research project will take. The problem statement should be clear and unambiguous, express a relationship between two or more variables, identify the population to be studied and encourage empiric testing. It introduced early in the research and should reflect a well-defined specific focus.
answer
Problem statement
question
has no right answer
answer
The study of values
question
or properties that vary from each other, are the focus of the study. For example a researcher studying postoperative patients might be interested in preoperative preparation in relation to the outcome of respiratory function. Variables can be dependent or independent, according to their role in a particular study.
answer
Variables
question
Has the presumed effect on the dependent variable. It may be manipulated if the researcher is doing an experimental study; in a nonexperimental study, it is assumed to have occurred naturally before or during the study.
answer
Independent variable
question
Is what you believe might be influenced or modified by the independent variable or it is the consequence of presumed effect that varies as changes occur in the independent variable. The dependent variable is the one that the researcher is interested in understanding and explaining.
answer
Dependent variable
question
Testability. If the question is posed in such a way that there is a relationship between an independent and a dependent variable and that relationship can be measured, it is likely that the question can be researched
answer
What is the final consideration when evaluating a research problem?
question
Is the overall plan for the collection and analysis of the data. The study's design is crucial. If the design can limit the number of research problems before the study, the outcome may be more useful. If an instrument is to be used in a study or a new instrument needs to be developed, a consultant in methods (a methodologist) can alleviate some reliability and validity problems by helping the novice researcher select or develop the instrument.
