The IDB Analyzer generates SPSS or SAS syntax files that take into account information from the complex sampling design of the study to produce population estimates. The IDB Analyzer was originally designed to allow users to combine and analyse data from IEAвЂ™s large-scale assessments, but it has been adapted to work with data from most major large-scale assessment surveys, including those conducted by the Organisation for Economic Co-operation and Development (OECD), such as the Programme for the International Assessment of Adult Competencies (PIAAC), the Programme for International Student Assessment (PISA), and the Teaching and Learning International Survey (TALIS). 6.1 The IDB AnalyzerДeveloped by IEA Hamburg, the IDB Analyzer is an interface that creates syntax for SPSS (IBM 2013) and SAS (SAS 2012). For each of these two sections, we will provide a description of the functionalities of the respective modules and examples to illustrate some of the capabilities of the IDB Analyzer (Version 4.0) to merge files and to compute a variety of statistics, including the calculation of percentages, averages, benchmarks (proficiency levels), linear regression, logistic regression, correlations, and percentiles.

1 Sections 6.2 and 6.3 will be dedicated to the Merge and Analysis modules of the IDB Analyzer, respectively. In the first section, we will provide a brief overview of the software. This chapter is subdivided into three main sections. 2 in this volume for details about PIAACвЂ™s complex sample and assessment design). Furthermore, it seamlessly takes into account the sampling information and the multiple imputed achievement scores to produce accurate statistical results (see Chap.

The IDB Analyzer provides a user-friendly interface to easily merge the data files of the different countries participating in PIAAC. You have merged your both data sets based on theВ key variable/ID.This chapter describes the general use of the International Association for the Evaluation of Educational AchievementвЂ™s (IEA) International Database Analyzer (IDB Analyzer) for analysing PIAAC data (IEA 2019). YouвЂ™ll see the information on the first data set before theВ key variable/ID and the information of the second data set afterВ theВ key variable/ID. If there is no error, SPSS will take you to the merged file. SPSS will show you a warning вЂњKeyed match will fail if data are not sorted in ascending order of Key Variables.вЂќДЇinally, Click on OK. Click on the Active dataset is keyed table. EnterВ theВ key variable/ID into Key Variables box clicking on the adjacent rightВ arrow. Click on Match cases on key variables in sorted files. Click on theВ key variable/ID from the Excluded Variables list. Browse your second file and click on continue. YouвЂ™ll see aВ dialogue box with the message вЂњAdd variable toвЂ¦вЂ¦.вЂќ Select An external SPSS Statistics data file. Click on Data and then select Merge Files. Now open the data set where you want to see the whole data after merging. Now you are ready to merge your desired data sets into one file. Sort theВ key variable/ID of two data sets in ascending order. Remove any duplicate case from the data sets. Set the same property forВ the key variable/ID in the two data sets. First of all, open both of your data sets.
