, What do correlational studies examine? Correlational studies examine relationships between variables, often using
Pearson R or Spearman Rho.
What is the function of inferential studies? Inferential studies determine differences between groups using tests like the
independent t-test and ANOVA.
What does a Pearson R value of 0.7 indicate? It indicates a strong linear relationship between two variables.
What is the difference between cluster sampling and Cluster sampling selects groups as subjects, while convenience sampling
convenience sampling? selects available participants.
What is the target population in research? The target population is the group for which study outcomes are intended.
What is gray literature? Gray literature refers to unpublished evidence not included in commercial or
academic databases.
What is evidence-based practice (EBP)? EBP is the conscientious use of research-based information in decision-making
about patient care.
What are the limitations of evidence-based practice? Limitations include a shortage of coherent evidence, difficulties in applying
evidence, and barriers to high-quality medicine.
What does the term 'impact factor' refer to? Impact factor gauges the quality of research by calculating the yearly average
of citations for articles in a journal.
What is the hierarchy of nursing research evidence? It ranks evidence from strongest (clinical trials) to weakest (expert opinion).
What is the significance of a study's limitations? Limitations must be considered when critiquing a study, as they can affect the
validity of the findings.
What is the purpose of the PICO question in research? PICO helps formulate research questions by identifying the Population,
Intervention, Comparison, and Outcome.
What does a correlation of -0.4 represent? It represents a moderate negative relationship between two variables.
What is the role of authors' credentials in research Authors' credentials indicate their expertise and qualifications, which contribute
articles? to the credibility of the research.
What is the difference between research utilization and Research utilization incorporates research into practice, while evidence-based
evidence-based practice? practice integrates clinical expertise with the best available evidence.
What is the purpose of qualitative studies in research? Qualitative studies assess thematic responses and rigor, focusing on credibility
and generalizability.
