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

  1. A researcher wants to determine if a new training program causes improved performance. Which design best supports a causal inference?

    Answer: Randomized controlled experiment

    Only randomized controlled experiments allow causal inference by ruling out alternative explanations through random assignment.

  2. What does a negative skew in a distribution of performance scores indicate?

    Answer: Most scores cluster near the high end with a tail toward the low end

    Negative skew means the tail extends to the left (lower scores), with most scores concentrated at the high end.

  3. In a multiple regression, which statistic indicates the unique contribution of each predictor while controlling for all others?

    Answer: Standardized beta coefficient

    Standardized beta coefficients reflect each predictor's unique contribution to the outcome after partialing out shared variance with other predictors.

  4. Which threat to internal validity occurs when participants change simply due to the passage of time during a study?

    Answer: Maturation

    Maturation refers to natural changes in participants over time that are unrelated to the experimental treatment.

  5. An I-O psychologist uses experience sampling methodology (ESM). What is the primary advantage of this approach?

    Answer: Captures within-person variability across time and situations

    ESM repeatedly measures individuals in real time, capturing fluctuations in mood, engagement, or behavior across contexts.

  6. When comparing the means of three or more independent groups, the appropriate statistical test is:

    Answer: One-way ANOVA

    One-way ANOVA tests for differences among three or more group means while controlling the familywise Type I error rate.

  7. A researcher reports a 95% confidence interval for a mean difference of [0.2, 1.8]. What can be concluded?

    Answer: The population mean difference is likely not zero

    A 95% CI that excludes zero suggests the population mean difference is unlikely to be zero, supporting statistical significance.
