Supplementary Information for Predicting Maths Anxiety From Mathematical Achievement Across the Transition From Primary- to Secondary-Education from Predicting maths anxiety from mathematical achievement across the transition from primary to secondary education

Table 1 shows the pattern of missing data for predictors of maths anxiety. Table 2 shows the main model from the paper (Table 4 in the main paper) but conducted on standardized scores. The parameter estimates in this table are, therefore, standardized coefficients. Similarly, Table 3 shows the *post hoc* analysis from the paper (Table 5 in the main paper) but conducted on standardized scores.
