Transdisciplinary Measurement & Evaluation Research Group (TMERG) Workshop #1 2018

The Transdisciplinary Measurement and Evaluation Research Group (TMERG) has its origins in the School of Education and provides an avenue for discussion and research collaboration in the field of measurement and evaluation across a number of Schools and Disciplines. Colleagues and postgraduate students (doctoral and master's) in your School/Research Centres are invited to a seminar titled:

WORKSHOP SERIES 2018: Workshop #1

SPEAKER: Ainun Najib Alfatih: MEd Program, School of Education – UofA

Introduction to analysing large scale assessment data (PISA/TIMSS/PIRLS) using WesVar 5.1

Scope/Abstract:

Sampling framework is a pertinent facet of research and provides an understanding of (complex) sample designs. The results of analyses conducted with statistical software applications, which are based on the assumption of simple random sampling, could be misleading especially when the sample design incorporates stratification, nesting/clustering, and multistage sampling. Missing data and the assignment of weights at various levels (for example, student, teacher/school, and country), if not scrutinised carefully, may confound analyses, associated inferences, and lead to erroneous conclusions. This workshop introduces complex sample designs, related statistical techniques and to address the concerns listed above.
The hands-on activities will utilise WesVar 5.1 (Westat, Inc.) for the following:
1. Examine sampling framework, sample designs, missing data, and weights
2. Setup of WesVar data file (moving data and variables from SPSS/SAS)
3. Compute descriptive statistics
4. Calculate mean score, standard errors, and associated statistics
5. Undertake t-test and interpretation of results
6. Estimate strength of association (correlation coefficients)
7. Undertake regression analysis and reporting (APA)
8. Understand basic mediation and moderation effects through WesVar
If you are using or planning to use international large-scale assessment dataset (PISA, TIMSS, PIRLS, TALIS), this workshop will provide an understanding of methods and techniques used for their reports.
