“Поиски лучшей репрезентации”: сравнение телефонных и квартирных опросных методик в социально-политических исследованиях (методический эксперимент)
The article discusses the results of a method- ological experiment conducted by Levada-Center in December 2014, in which author analyzes ad- vantages of face-to-face and telephone sampling method for representation of socio-demographic and electoral variables. There were a comparison of random-digit dialing (RDD) sample of cell and landline telephones and random route face-to-face sample of 500 Muscovites in each method.
The results of experiment show the statistical difference between two samples of the core ques- tions of the survey. While basic demographic vari- ables are the same in both samples (employment, access to the Internet, number of cell and landline phones, presence of travelling abroad passport), larger differences emerge on measures of politi- cal and social engagement. The respondents of telephone survey more involved in the discussion of political issues and looking for such informa- tion and they have more level of civic engagement – 23% saying that they did some type of volunteer work for or through an organization in the past year, compared with 11% who report doing this in face- to-face survey. They are also more likely to know a foreign language and have a surpass representation of the group of high-income (26% compared to 6% in door-to-door survey).
However, despite these differences in interest in politics and lifestyle, both samples were similar across all socio-political issues - in their attitude to democracy, willingness to participate in the elec- tions and their electoral preferences.
