Read the first 7 Research Methods & Data Analysis in I-O Psychology flashcards as text

  1. An I-O researcher finds a statistically significant result with p = .04 but a Cohen's d of 0.08. What is the most accurate interpretation?

    Answer: The effect is statistically significant but practically trivial

    A very small effect size (d = 0.08) indicates minimal practical significance even when the result is statistically significant, often due to large sample size.

  2. Which threat to external validity occurs when the effect of a treatment is specific to the type of people who volunteered for the study?

    Answer: Interaction of selection and treatment

    The interaction of selection and treatment limits generalizability when findings only hold for the specific volunteer sample studied.

  3. Which reliability estimate is most appropriate for assessing the consistency of a single administration of a test?

    Answer: Coefficient alpha (Cronbach's α)

    Coefficient alpha estimates internal consistency reliability from a single administration by examining inter-item correlations.

  4. A researcher controls for a variable by including it as a covariate in ANCOVA. What is the primary goal of this procedure?

    Answer: Remove variance due to the covariate to clarify treatment effects

    ANCOVA statistically removes variance attributable to the covariate, reducing error variance and isolating the treatment's effect.

  5. Which type of research question is best answered using qualitative methods rather than quantitative methods?

    Answer: How do employees make sense of a corporate merger?

    Qualitative methods are best suited for exploring how and why questions, including how individuals interpret and give meaning to events.

  6. In structural equation modeling (SEM), what does a latent variable represent?

    Answer: An unobserved theoretical construct inferred from indicators

    Latent variables in SEM represent hypothetical constructs that are estimated from multiple observed indicator variables.

  7. Which index in confirmatory factor analysis (CFA) indicates acceptable model fit when its value is ≥ .90?

    Answer: Comparative Fit Index (CFI)

    CFI values of .90 or higher (with .95+ preferred) indicate that the proposed model fits the data acceptably.
