Read the first 7 Research Methods & Evidence-Based Practice flashcards as text

  1. What is the primary purpose of a control group in an experimental research design?

    Answer: To provide a baseline comparison unaffected by the experimental treatment

    A control group receives no treatment or intervention, providing a baseline against which to measure the effect of the experimental variable.

  2. Which sampling method ensures every individual in a target population has an equal and independent chance of being selected?

    Answer: Simple random sampling

    Simple random sampling assigns an equal probability of selection to every member of the population, minimizing selection bias.

  3. In research methodology, what does the term 'validity' refer to?

    Answer: The degree to which a tool measures what it is intended to measure

    Validity refers to how accurately an instrument or method measures the specific concept it is designed to assess.

  4. What is triangulation in qualitative research?

    Answer: Using multiple data sources or methods to strengthen findings

    Triangulation involves cross-verifying findings using multiple methods, sources, or investigators to improve credibility and reduce bias.

  5. Which research design is most appropriate when trying to establish a cause-and-effect relationship between variables?

    Answer: Randomized controlled experiment

    A randomized controlled experiment (RCT) is the gold standard for establishing causality because random assignment controls for confounding variables.

  6. What is the main purpose of conducting a pilot study before a full-scale research project?

    Answer: To test and refine procedures, instruments, and feasibility

    A pilot study is a small-scale preliminary investigation that identifies procedural problems and allows refinement before committing to a full study.

  7. In research, what does 'operationalization' of a variable mean?

    Answer: Defining a variable in measurable, observable terms

    Operationalization specifies exactly how an abstract concept will be measured or manipulated in a study, making it observable and quantifiable.
