Fig. 4: Prediction of a × b-paths for mediator self-perceived competency by social mobility index.
From: Self-perceptions as mechanisms of achievement inequality: evidence across 70 countries

The indirect effect (path a × b) via self-perceived reading competency is predicted by countries’ social mobility index using a meta-analytic approach across n = 57 countries; y-axis expresses effect in PISA points (M = 500, SD = 100).
