Review Test Submission: Module 2 Quiz 2192-NURS-5366-407-PRINC-OF-RESEARCH-IN-NURSING--2019-Spring d. A previous history of his work written about him Response Feedback : The published literature contains primary and secondary sources. A primary source is written by the person who originated, or is responsible for generating, the ideas published. A research publication published by the person or people who conducted the research is a primary source. A theoretical book or paper written by the theorist who developed the theory or conceptual content is a primary source. A secondary source summarizes or quotes content from primary sources. Thus, authors of secondary sources paraphrase the works of researchers and theorists. The problem with a secondary source is that the author has interpreted the works of someone else, and this interpretation is influenced by that author’s perception and bias. Authors have sometimes spread errors and misinterpretations by using secondary sources rather than primary sources. You should use mostly primary sources to write literature reviews. Secondary sources are used only if primary sources cannot be located or if a secondary source contains creative ideas or a unique organization of information not found in a primary source.

The dependent variable (response or outcome variable) is measured to examine the effect created by the independent variable. An independent variable is a stimulus or activity that is manipulated or varied by the researcher to create an effect on the dependent variable. A dependent variable is the response behavior or outcome that the researcher wants to predict or explain. Extraneous variables exist in all studies and can affect the measurement of study variables and the relationships among them. Extraneous variables are of primary concern in quantitative studies, because they can obscure one’s understanding of the relational or causal dynamics within the studies. The extraneous variables that are not recognized until the study is in process or are recognized before the study is initiated but cannot be controlled are referred to as confounding variables. Demographic variables are attributes of the subjects that are measured during the study and used to describe the sample.
