Political party ratings in the parliamentary elections, December 2020: a comparison of telephone survey and face-to-face interview results

In the first of December 2020, the Kyiv International Institute of Sociology (KIIS) jointly with the Democratic Initiatives Foundation conducted an experiment by comparing the ratings of political parties that were gleaned from in-person interviews (a study that was commissioned by the Foundation) and telephone interviews (that KIIS did for its Omnibus). Both surveys had the same sample size of 2,000 respondents, asked the same phrased questions and had the same party lists. In both cases, the question was the first in the questionnaire so that the influence of other questions was eliminated. Also, the survey was conducted practically during the same time period: the face-to-face interviews were held on December 5-13 and the telephone interviews took place on December 4-8. The only difference is that the Democratic Initiatives’ face-to-face survey was based on a random sample at the first stages of selection with quota selection at the last stage. The KIIS survey was based on the main sample of randomly generated mobile numbers (that were not selected from a specific database) without additional quotas, with only people who are 18 years or older living on Ukrainian territory being polled.
