  1. Which type of validity evidence is gathered by examining correlations between a measure and theoretically related and unrelated constructs?

    Answer: Convergent and discriminant validity

    Convergent validity is shown by high correlations with related constructs; discriminant validity by low correlations with unrelated constructs.

  2. In meta-analysis, what does the Q statistic test?

    Answer: Heterogeneity of effect sizes across studies

    The Q statistic tests whether observed variance in effect sizes across studies exceeds what is expected by sampling error alone.

  3. A job analysis reveals that a selection test measures knowledge not needed until 6 months on the job. This is most relevant to which type of criterion-related validity?

    Answer: Predictive validity

    Predictive validity involves measuring a predictor now and relating it to future criterion performance, making the timing concern relevant.

  4. What is the primary purpose of conducting a pilot study before a large-scale survey?

    Answer: To identify flaws in survey items and procedures

    Pilot studies reveal ambiguous items, poor response formats, and procedural problems before full deployment.

  5. Which data collection method is most susceptible to demand characteristics?

    Answer: Self-report questionnaires in a lab

    Lab self-report measures are most vulnerable because participants may guess study hypotheses and respond accordingly.

  6. In hierarchical regression, a researcher adds a block of predictors in Step 2. The change in R² (ΔR²) represents:

    Answer: Variance explained by Step 2 predictors above and beyond Step 1

    ΔR² in hierarchical regression reflects the incremental variance explained by the new block of predictors over those entered in prior steps.

  7. Which sampling strategy ensures every member of the population has an equal probability of selection?

    Answer: Simple random sampling

    Simple random sampling assigns each population member an equal probability of being chosen, supporting representativeness.
