reflect a quantitative methodology

A total of two annotated bibliographies are to be submitted (not to exceed one page each). The articles must come from nursing scholarly literature and may not be older than 5 years since publication. Please note that the articles must be research based and reflect a quantitative methodology (review our reading assignments). Web pages, magazines, textbooks, and other books are not acceptable.
Each annotation must address the following critical elements:
Explanation of the main purpose and scope of the cited work
Brief descriiption of the research conducted
Value and significance of the work (e.g., study’s findings, scope of the research project) as a contribution to the subject under consideration
Possible shortcomings or bias in the work
Conclusions or observations reached by the author
Summary as to why this research lends evidence to support the potential problem identified specific to your role option
My role is a family nurse practitioner.

Quantitative Methods
Quantitative designs can either be descriiptive, correlational, quasi-experimental, or experimental. While descriiptive studies only describe the variables as they are found, correlational research examines relationships among variables. Experimental research and quasi-experimental research examine causal relationships between variables of interest.
Descriiptive Research
• Conducted to describe new situations, events or concepts
• Conducted without researcher control because subjects are examined as they exist in their natural setting
• The outcomes of descriiptive research include the descriiption of concepts, identification of relationships and development of hypotheses that provide a basis for future quantitative research
Correlational Research
• Conducted to examine relationships among concepts or ideas, such as the relationship between wine consumption and cholesterol level
• Involves the systematic investigation of relationship between or among two or more variables
• Primary intent is to explain the nature of relationships in the real world, not to determine cause and effect
• Correlation is not Causation
Quasi-Experimental Research
• Conducted to examine causal relationships or determine the effect of one variable on another
• Involves implementing a treatment and examining the effects of this treatment
• Quasi-experimental studies differ from experiment studies by the level of control achieved
• When studying human behavior, researchers are frequently unable to manipulate or control certain variables or settings
Experimental Research
• Objective, systematic, controlled investigation
• Tests the effectiveness of various treatments under strictly controlled conditions
• Often associated with studies of animals in laboratory settings
• Used for the purpose of predicting and controlling phenomena
• Causality between the independent and dependent variables is examined under highly controlled conditions
• Most powerful quantitative method
Three Things Necessary for Experimental Research
• Controlled manipulation of at least one treatment variable (independent or experimental variable)
• Exposure of some subjects to the treatment (experimental group) and some not exposed (control group)
• Random selection of subjects for the study.
