100% CORRECT
What is inferential analysis - ANSWER>•Statistical tests to determine if results found in a sample
are representative of a larger population.
•Inferential analysis is undertaken to determine if a specific result can be expected to occur in a
larger population, given that it was observed in a sample.
•In statistics, a sample (part of the population) is used to represent a target population (all of
the population); the question then becomes whether the same results found in the sample
would be found in the larger target population.
•Quantitative research as evidence for practice is useful only when it can be generalized to
larger groups of patients than those who were directly studied in the experiment. Inferential
analysis allows the nurse to recommend that an intervention be used and to do so with an
identified level of confidence that it is evidence based.
, Applicability and transferability - ANSWER>•The feasibility of applying qualitative research
findings to other samples and other settings.
•Replicability: - ANSWER>•The likelihood that qualitative research outcomes or events will
happen again given the same circumstances.
What is internal validity and what are some of the threats? - ANSWER>•The confidence that an
experimental treatment or condition made a difference and that rival explanations were
systematically ruled out through study design and control.
Threats include: History, Maturation, Testing, Istrumentation, Consent, Treatment, Multiple
Treatments, Subject selection, and attrition
How do you determine which research design to use? - ANSWER>•Is a strategy for answering
your research question using empirical data.
•Your overall research objectives and approach
•Whether you'll rely on primary research or secondary research
