4. ICCS 2009 IDB Workshop, 18 th February 2010, Madrid Introduction to IDB Analyzer WHAT IT IS –A software program developed by the IEA Data Processing and Research Center to analyze the data from ICCS and other IEA surveys –Calculates correct standard errors when conducting analysis with ICCS –Uses optimized algorithms for computing means, percentages and regressions BONUS! –Easy creation of data sets for use in SPSS –Merging countries and/or data levels –Selection of analysis variables

5. ICCS 2009 IDB Workshop, 18 th February 2010, Madrid What can it do? For ICCS, compute percentages, means (and SD), correlations, and linear regressions – including their respective standard errors Allows to analyze data calculating the correct standard errors using JRR (jackknife repeated replication) Enhanced SPSS and MS Excel output including adding titles to tables and column labels

6. ICCS 2009 IDB Workshop, 18 th February 2010, Madrid Why Do We Need IDB Analyzer? Very common question: “Why can’t I just do this in SPSS?” Answer: “Because of the data structure!” –Sampling is multi-stage, clustered, and stratified which can not be handled correctly by SPSS (remember the sample design presentation) –SPSS can not do variance estimation based on replicated weights IDB Analyzer handles these issues and “adds” the missing features to SPSS!
