Simple slopes analysis examines the relationship between a predictor and outcome at what levels of a moderator?

• A. It assesses the effect of a moderator only at the mean value.
• B. It analyzes the relationship at low, mean, and high levels of the moderator.
• C. It estimates the overall effect of the predictor ignoring the moderator.
• D. It tests equal slopes across groups.

Answer: (B)

Simple slopes analysis probes how the effect of a predictor on an outcome changes across levels of a moderator by estimating that relationship at specific moderator values. It typically evaluates the slope at low, mean, and high levels of the moderator, so you can see whether the predictor’s impact is stronger or weaker depending on where the moderator sits. This helps you interpret an interaction: you can observe if the predictor matters more when the moderator is high, and less when it is low. If you only looked at the effect at the mean, you’d miss how the relationship changes across different moderator values; ignoring the moderator altogether would miss the interaction, and testing for equal slopes wouldn’t describe the conditional effects that simple slopes provides.
