Course description

Registration deadline: 05.04.2027
Registration after this date might be possible, but is subject to sufficient demand and availability of places.

Social, political, and economic issues are typically complex and influenced by many factors. In social science research, it is difficult to disentangle the importance of different factors and to test corresponding theories. This includes survey research when standard survey items are used to measure determinants of normative beliefs, attitudes, preferences, behavioral intentions, etc. Often, all factors appear to be important, and responses are prone to social desirability.

In factorial survey experiments (FSEs), participants are asked to evaluate descriptions of a situation that are experimentally varied on multiple factors/attributes, and participants have to make trade-offs between attributes. FSEs offer therefore a way to disentangle the importance of attributes and reduce social desirability bias. FSEs can also be used to test theories and mechanisms, and they have been applied to a wide range of issues in both the Global North and the Global South, including social acceptance of environmental policies, the perceived fairness of the gender pay gap, and normative beliefs about marriage and child education.

This course will introduce FSEs, and you will become familiar with the theoretical underpinnings and empirical applications of these experiments, as well as learn how to design experiments, collect and analyze FSE data. The course will combine lectures with hands-on sessions using R; for most examples, Stata syntax will be provided. You will have the opportunity to discuss your own research projects/ideas.

Organizational structure of the course

Each day, there will be three hours of input from the lecturers, combined with three hours of practical sessions. The maximum for each input is 45 minutes. The inputs will introduce the main topics such as theoretical foundations, experimental design, questionnaire design and implementation, data analysis and interpretation. All topics will be illustrated with examples, and you will be encouraged to ask questions and contribute to the discussion. The hands-on sessions will allow you to apply these topics in groups or, if preferred, individually using R (for most topics, Stata syntax can be provided). During these sessions, the lecturers will be available for questions and discussion. You will also have the opportunity to discuss your individual projects and/or research problems with the lecturers.

Target group

You will find the course useful if:

you want to learn more about factorial survey experiments, their potential and pitfalls,

you want to learn how to design and analyze factorial survey experiments,

you are planning a specific application of factorial survey experiments,

you are a postgraduate student or researcher, senior researcher, quantitative social scientist working in the public or private sector.

Learning objectives

By the end of the course, you will:

have a good understanding of the (theoretical) foundations of factorial survey experiments,

have a good understanding of the conditions under which factorial survey experiments are applied,

know the foundations of experimental designs for factorial survey experiments,

know how to conduct a factorial survey experiment, including survey design,

be able to build a dataset for factorial survey experiments,
