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

  1. A tutor wants to know if there is a relationship between hours of practice and test scores without manipulating any variable. The appropriate design is:

    Answer: Correlational study

    Correlational studies examine relationships between variables without any manipulation, identifying associations but not causation.

  2. Which ethical principle requires tutors using human subjects research to obtain informed permission from participants or their guardians?

    Answer: Informed consent

    Informed consent ensures participants understand the study's purpose, risks, and their right to withdraw before agreeing to participate.

  3. A positive correlation coefficient of r = 0.85 between study time and quiz scores means:

    Answer: As study time increases, quiz scores tend to increase

    A positive r indicates that as one variable increases, the other tends to increase, though correlation does not imply causation.

  4. A tutor notices that after implementing a new intervention, students' scores improved, but scores were unusually low right before the intervention began. This confound is called:

    Answer: Regression to the mean

    Regression to the mean occurs when extreme scores naturally move toward the average on subsequent measurement, mimicking intervention effects.

  5. Which component of a research article describes the statistical procedures used and how data were collected?

    Answer: Methods section

    The methods section provides enough procedural detail for study replication, including participants, measures, and analysis procedures.

  6. In an ABA single-subject design, the second 'A' phase serves to:

    Answer: Withdraw the intervention to confirm its effect

    Returning to the baseline (A) condition after intervention demonstrates that behavior changes were due to the intervention, not extraneous factors.

  7. A tutor reviews two studies: one shows significant results with n=12, another shows non-significant results with n=200. Which concern does this raise?

    Answer: The small study may have achieved significance due to chance (Type I error)

    Small samples are more susceptible to Type I errors (false positives), meaning a significant result may not replicate in larger samples.
