Illustration of within-person and between-person relationships between two variables. Each ellipse represents the data from a single person. Dashed lines represent the between-person slope (i.e., βB), which may have a different sign as the within-person slope (Left panel), may be similar to the (average or fixed) within-person slope (Middle panel), or may be larger than the (average or fixed) within-person slope (Right panel).
