In order to obtain adequate answers to your research questions, the data must be prepared and processed in line with your research questions. Our GESIS experts will be happy to advise you on this process. Our consulting services include the calculation of design and adjustment weights for a suitable estimate for the target population, the imputation of missing values, and the handling of non-response bias. If you use different data sources for comparison, harmonisation of socio-structural or content variables is unavoidable. Here, too, you can count on our consulting expertise.
We have compiled various sets of information and hands-on guidelines on frequently occurring consulting topics. These already answer many questions that may arise when planning a study and collecting data. You can find this information under Basic Knowledge.
