Questionnaire Testing and Design

The purpose of questionnaire testing and design is to improve the internal quality of statistics by developing data collection methods. By internal quality we mean the relevance, comparability and interpretability of statistical data. Careful planning of data collection will also lower the response burden of data suppliers and the need for post-processing of data.

The Questionnaire Testing and Design Unit offers the following services for evaluating the quality of data collection:

  • Study and testing of concepts, classifications and data collection questionnaires and methods
  • Training and consultation
  • Publications

We evaluate survey responding using qualitative methods - focus group interviews, expert panels, cognitive interviews and behavioural coding. We perform quality evaluation both when planning data collection and during the actual collection in our modern laboratory facilities and technical equipment. We follow and contribute to international development in our field and utilize the latest methods. We provide consultation and training on the internal quality of data collection.

We distribute new knowledge in the field by training and publishing in Statistics Finland's Tieto&trendit – talous- ja hyvinvointikatsaus periodical and other journals.
