Question 1

Which of the following best describes the purpose of bootstrapping in mediation analysis?

Accepted Answer

To estimate the sampling distribution of the indirect effect without assuming normality

Answer

Bootstrapping resamples the data repeatedly to construct an empirical sampling distribution for the indirect effect, providing more accurate confidence intervals.

Question 2

A moderator variable in a regression context is indicated by:

Accepted Answer

A significant interaction term between predictor and moderator

Answer

Moderation is evidenced by a significant interaction term, indicating that the predictor-outcome relationship differs across levels of the moderator.

Question 3

An organization collects supervisor ratings and subordinate self-ratings of performance. The low correlation between them is best explained by:

Accepted Answer

Rater perspective differences and unique information

Answer

Supervisors and subordinates observe different behaviors and have access to different information, which typically produces low convergence.

Question 4

What is the key statistical assumption underlying the use of parametric tests like ANOVA and t-tests?

Accepted Answer

Data are drawn from normally distributed populations

Answer

Parametric tests assume that the data come from populations with normal distributions, though they are robust to moderate violations with large samples.

Question 5

Which approach to handling missing data is generally superior to listwise deletion when data are missing at random (MAR)?

Accepted Answer

Multiple imputation

Answer

Multiple imputation creates several plausible datasets reflecting uncertainty about missing values, yielding unbiased estimates under the MAR assumption.
