PRIDI 2013 Data
Data analysis
- All statistics were computed using appropriate sampling weights.
- Estimation of standard errors for significance testing were computed by means of:
- Replication methods (jackknife repeated replication) to estimate sampling variance, and
- Five plausible values for estimating measurement variance.
Secondary analysis
For doing secondary analyses, data can be analyzed with the IEA IDB Analyzer and the International Data Explorer. These tools take into account the characteristics of the sampling and assessment design in order to implement the appropriate replication method, and they make use of existing plausible values.
