The big picture: Correlation and the Standardized Slope
What does a one-predictor slope add to correlation?
Why a policy analyst should care
Correlation and a simple slope describe the same linear association on different scales, clarifying what changes when units are standardized or retained.
Follow the idea from the opening question to a practical decision. These are the conceptual moves this module will develop:
1 Question What does a one-predictor slope add to correlation?
2 Explore Rescale the predictor
3 Formalize Slope and correlation are connected
4 Transfer Report a meaningful slope
