This project is a continuation of the research “Public opinion research methods in a new technological and social environment I.”. Based on Hungarian population parameters (regional internet penetration data, composite respondent attitudes and socio-demographic composition estimates), we implemented the international guidelines necessary for the correct and reliable conduct of research using online questionnaire data collection and data interpretation. We carried out simulation studies in order to highlight research questions for which online survey data can be used and the topics for which it may be misleading. Using face-to-face survey data, we defined theoretical subsamples of the population available offline and online, as well as evaluated the estimates derived from them.

The project was successfully completed in the first quarter of 2024, with the results summarized in a complex dashboard. In this, we interactively illustrate the data and results detailed above, which we made available to both the scientific and civil spheres. The dashboard is available on the research group's Tableau Public profile.

In addition, the poster below shows how estimates based on online surveys can be biased, and how the combined use of online and offline survey methods can improve results.
