a careful examination of all aspects of a study to judge its strengths, limitations, meaning, and significance. What is evidence-based practice? Evidence-based practice evolves from the integration of the best research evidence with clinical expertise and patients' needs and values.
Page 3 of 12 Ch.2 What is descriptive research? the exploration and description of phenomena in real-life situations. It provides an accurate account of characteristics of particular individuals, situations, or groups. Remember, this type of study does not show cause and effect. What is correlational research? the systematic investigation of relationships between or among variables. Using correlational analysis, the researcher is able to determine the degree or strength and type (positive or negative) of relationship between two variables. Remember, this type of study does not show cause and effect. What is quasi-experimental research? it examines causal relationships or determines the effect of one variable on another. These studies involve implementing a treatment and examining the effect of the treatment using selected methods of measurement. What is experimental research? an objective, systematic, highly controlled investigation for the purpose of predicting and controlling phenomena in nursing practice. Causality between the independent and dependent variables is examined under highly controlled conditions. What are the three main characteristics of experimental research? controlled manipulation of at least one treatment variable (the independent variable), exposure of some of the subjects to the treatment (experimental group) and no exposure of the remaining subjects (control group), and random assignment of subjects to either the control or the experimental group. What is basic or "pure" research? scientific investigation that involves the pursuit of knowledge for knowledge's sake, or for the pleasure of learning and finding truth What is applied or "practical" research? scientific investigation conducted to generate knowledge that will directly influence or improve clinical practice. The purpose of this type of research is to solve problems, make decisions, or predict or control outcomes in real life practice situations. These findings can also be useful to policy makers as a basis for making changes to address health and social problems. What is rigor in quantitative research? Rigor is striving for excellence in research, and it requires discipline, adherence to detail, and strict accuracy. A rigorously conducted quantitative study has precise measuring tools, a representative sample, and a tightly controlled study design. What is precision in quantitative research? Precision encompasses accuracy, detail, and order. It is evident in the concise statement of the research purpose and detailed development of the study design.
Page 4 of 12 The most explicit example of precision is the measurement or quantification of the study's variables.
