Advanced Data Analysis Using the IEA’s IDB Analyzer

Objective
The IEA’s IDB Analyzer is a standalone application that generates syntax in SAS and SPSS that can be used to analyze large-scale assessment databases such as those published by the IEA (TIMSS, PIRLS, ICCS, etc.) and OECD (PISA and PIAAC). This workshop will focus on the use of the of the linear and logistic regression statistic modules that are part of the IDB Analyzer. In particular, it will review different types of analysis that can be conducted with these modules and demonstrate the users how

to interpret the output.

Procedures

The workshop will consist of a combination of lectures and hands-on. The lectures will provide a quick overview of the theoretical underpinnings of linear and logistic regression, and the key statistics that are generated with these analysis. It will also provide the participants with a handful of exercises where they will get to explore and use different features of the analysis module. Participant will be requires to have a working version of SAS or SPSS installed on their computer.

Expected Outcomes for Participants

After the workshop participants will be able to:

• Use the IDB Analyzer to specify a linear of logistic regression analysis using large-scale scale assessment data
• Interpret the output created by the IDB Analyzer with the linear and logistic regression modules.

Target Audience
The workshop builds on prior knowledge of linear and logistic regression analysis. Familiarity with SPSS or SAS as well as large scale data is expected. Sample data from most recent TIMSS international

database will be distributed to be used in the hands-on examples.

Requirements - IMPORTANT

• You are only eligible to attend this workshop if you are registered as participant of ECER.
• Participants have to bring their own computers with a working version of SAS or SPSS. They will also need to have a working version of the IDB Analyzer. See www.iea.nl/our-data.

Recommended Reading
Technical documentation for studies such as TIMSS, PIRLS, ICCS or PISA.
