SD of literacy, low education 0.539 0.641 0.054 0.241
SD of literacy, interm. education 0.876 − 0.252 0.020 0.112
SD of literacy, high education 0.844 − 0.185 − 0.078 0.124
SD of numeracy, low education 0.617 0.607 0.075 0.202

  1. Factor analysis method is principal factor analysis. All values are averages across ten plausible values. SD = Standard deviation (as discussed in the text, this is the residual within-group standard deviation of literacy/numeracy skills after accounting for age, sex, and foreign-birth/foreign-language status)
  2. interm. intermediate
