SEA-PLM 2019 Data

Data analysis
  • All statistics were computed using sampling weights.
  • Estimation of standard errors for significance testing were computed by making use of:
    • Replication methods (jackknife repeated replication, JK2 variant) to estimate sampling variance, and
    • Five plausible values for estimating measurement variance.
  • General note: SEA-PLM data were designed for group-level reporting; students’ scale scores in the database are not intended to report performance of individual students or very small groups.
