| § This is a lower triangular symmetrical table. 1 At grade 12 only, the "measurement" and "geometry" subscales were combined for scaling. NOTE: Table values were obtained by computing a separate Pearson correlation coefficient for each plausible value, computing Fisher’s z transformation for each value, computing the average of the transformed values, and computing the inverse transformation.
