Survey Methodology Consulting: Survey Design and Sampling
The quality of data and their significance depend crucially on the type of sample design. In principle, two types can be distinguished here: Random samples (probability samples) and non-probability samples. Only random samples allow conclusions to be drawn from the sample to the target population. If this is not the goal of a study, non-probability samples can be a cost-effective alternative.
We are happy to consult you on planning the appropriate sample for your individual research project. The planning of the appropriate sample design as well as the corresponding sample size should be well-considered at the beginning of any survey and tailored to the target population (population), the survey instrument, and the general conditions of the research project (e.g. budget). GESIS supports you in this process by providing advice on sample designs and sample size planning.
