After establishing a correlational relationship between intelligence and academic performance, researchers can apply a simple ________ equation to calculate an individual's expected GPA given their specific IQ score.

An example of simple regression involves predicting a student's grade point average (GPA) based on their intelligence quotient (IQ) score. Once correlational research establishes a relationship between IQ and GPA, researchers can apply a simple regression equation to calculate an individual's expected GPA given their specific IQ score.

Simple regression is a statistical technique that involves using exactly one predictor variable to predict the value of a single outcome variable.

The equation for simple regression has the general form $$Y = b_1X_1$$. In this formula, $$Y$$ represents the predicted score on the outcome variable, $$X_1$$ represents the individual's score on the predictor variable, and $$b_1$$ represents the regression weight or the slope of the line.
