M11 - Multilevel Analysis for Grouped and Longitudinal Data

Target audience

This course targets professionals and investigators from diverse areas ranging from researchers in the behavioral and social sciences to whoever deals with data with a hierarchical or multilevel structure.


Social research often concerns relationships between individuals and the social contexts to which they belong. This can be conceptualized as a hierarchical structure, with individuals nested within groups.

Classical examples are educational research, with pupils nested within schools, and cross-national research, with individuals nested within their national units. They involve two level data: group level and individual level variables.

We need multilevel modeling to study the relationships between variables observed at different levels in the hierarchical structure.

This can also cover longitudinal research, by viewing measurement occasions as nested within respondents, and extends to situations where data have a more complex multilevel structure, such as cross-classified data or multiple-membership models.

This short course is intended as a basic and nontechnical introduction to multilevel analysis.

It starts with a description of some examples, and shows why multilevel models are necessary if the data have a hierarchical structure. It then covers the basic theory of two- and three-level models.

Next it explains how multilevel models can be applied to analyzing longitudinal data, and why and when this may be an attractive analysis approach, as compared to more classical analysis methods such as multivariate analysis of variance (Manova).

The cou​rse includes three computer labs, where multigroup and longitudinal data are analyzed. The computer labs in the course use the multilevel program HLM ​as a didactic analysis tool in combination with SPSS​, a free environment for statistical computing and graphics.

Course prerequisites

The course assumes reasonable familiarity with analysis of variance (as eg. taught in Module 5 of this year's program) and multiple regression analysis, but prior knowledge of multilevel modeling is not assumed.

Exam / Certificate

If you take part in all 6 sessions you will receive a certificate of attendance via e-mail after the course ends.

Additionally, you can take part in an exam. If you succeed in this test a certificate from Ghent University is issued.
The exam consists of a take home project assignment. You are required to write a report by a set deadline.
