  1. What type of study is classified as non-experimental or observational design? Aims to capture naturally occurring variations in the features of the phenomenon being studied.
    Descriptive research
  2. What are the elements, features, or characteristics of persons, experiences, situations, or things studied in descriptive research called
    variables
  3. What are healthcare providers interested in regarding variables?
    • Level in various populations
    • How they change over time
    • How they affect one another
  4. What is the term for measurement methods that consistently yields values close to the actual values
    Reliability
  5. What do researchers call it when a measurement method captures a high degree the totality of a variable of interest
    Valid
  6. What is the difference in readings caused by the difference in measurement technique called?
    measurement error
  7. What is the accurate capture of underlying concept
    Validity
  8. What three things suggest that Data is trustworthy
    • Appropriate choice of measurement instruments
    • Proven Measurement Instruments
    • Sound data collection procedures
  9. What are variables that may have influence in the situation but are outside the interest of study
    Extraneous Variables
  10. What do researchers use to minimize the effect of participation in a study by considering the order in which the data are collected and/or by giving equal attention to all groups whom data are collected
    Hawthorne Effect
  11. What is an interval with defined endpoints between which the means of many other samples are likely to lie
    confidence interval
  12. What does the confidence interval capture
    The true population mean
  13. What is random selection
    Everyone has an equal opportunity to be chosen
  14. What is a sample that is randomly selected from a list of population members
    simple random sampling
  15. What sampling type is used when the researcher wants to get data from subgroups of the population that are small and might not be present in sufficient numbers in a simple, random sample (STRATAS)
    Stratified Random Sampling
  16. What type of sampling is used when the target population is large and spread out and the researcher needs to concentrate data collections in a few locations
    Cluster sampling
  17. What type of sampling consists of an assumed population that is defined by demographic, disease, functional, symptom, or wellness characteristic (accessible to researcher)
    Convenience sampling
  18. Steps of convenience sampling
    • Assumed population
    • Presumed to be assumed
    • Conduct sample
    • Develop detailed profile of charecteristics
    • Statistical Inferences and generalizations
  19. What two things could the target population be
    • actual population (random)
    • projected population (convenience)
  20. What types of factors are taken into consideration when selecting sample size in a quantitative study
    • type of study
    • number of the variable
    • Statistics used
    • How much variability
    • Difference in comparison groups expected
    • Resources available for study
  21. Describe 3 issues that occur with surveys
    • Failure to obtain sample from target
    • Unclear questionaires to those taking survey
    • Low response rate (not representative)
  22. What is the most common way descriptive study reports the results
    percentages
  23. When would the mean verse the median be applied when reporting average scores in descriptive study results
    • Mean: when numbers are close together
    • Median: When there are outliers (skewed)
  24. What is the probability that the difference in the means being compared is just chance variation
    p value
  25. What are truth of findings as judged by participants and others within the discipline
    Credibility
  26. What is Accountability as judged by the adequacy of information leading the reader from the research question and raw data through various steps of analysis to the interpretation of findings
    Auditability
  27. What is faithfulness to everyday reality of the participants, described in enough detail so that others in the discipline can evaluate the importance for their own practice, research, and theory development
    Fittingness
  28. What are findings that reflect implementation of credibility, autditability, and fittingness standards
    Confirmability
  29. Name the four criterias of judging scientific rigor
    • Credibility
    • Auditability
    • Fittingness
    • Confirmability
  30. Name 4 types of quantitative research
    • Descriptive
    • Correlational
    • Quasi-experimental
    • Experimental
  31. What type of quantitative research looks at the relationship between 2 or more variables
    Correlational
  32. What type of quantitative research is less controlled by researcher, samples are not randomly selected, and examines cause and effect relationship
    Quasi-experimental
  33. What type of quantitative research is highly controlled, objective, systematic, measures independent and dependent variables, and looks at cause and effect relationship
    Experimental
  34. Name 3 characteristics of Experimental research
    • Controlled manipulation of at least 1 independent variable
    • Uses experimental and control groups
    • Random assignments
  35. What type of research seeks to solve real problems in clinical practice?
    Applied
  36. What type of reasoning is essential to rigor in quantitative research
    logical
  37. What two types of research have natural settings
    correlational and descriptive
  38. What is an area of concern needing research for nursing practice
    research problem
  39. What comes from the research problem and identifies a specific goal or aim in the study
    Research purpose
  40. What 3 things is included in the research purpose
    • Variables
    • Population
    • Setting
  41. What is the purpose of literacy review
    understanding what knowledge exists to make changes in practice
  42. What is the abstract, theoretical basis for a study that enables the researcher to link the findings to nursing body of knowledge
