Correlation 4 measures the relationship between the number of hours spent doing homework in the fall semester (a predictor) and the spring GPA (an outcome variable). This is an example of a cross-lag correlation because it considers how the predictor variable in one time period (fall) is related to the outcome variable in a later time period (spring).
