Dobewall 21 University of Goengen, Germany; 2 University of Tartu, EstoniaBilsky, Janik, and Schwartz (2010) concluded (1) a ”support [of] the circular structure of basic values …” (abstract),and (2) that ”the circular model fits somewhat less well in less developed sociees” (p. 16). We commenton the conclusions drawn from the data by focusing on the migang quanfier ”somewhat”.2.23 Assessing the Quality of Survey Data IIITo be held on July 20, 2011 from: 11:00 to 12:30, in room 410.Coordinated by: Jörg Blasius - University of Bonn, Germany2.23.1 Vive la différence: What are the Implicaons of Response Non-differenaon in Web-based Studies?R. Thomas 11 ICF Internaonal, United StatesResponse non-differenaon (also known as ’straight-lining’) occurs when respondents evaluate a series ofelements and give the same answer to each element. Non-differenaon has been proposed to result fromsurvey sasficing (Krosnick, 1999) which occurs when respondents select responses that minimally meet thedemands of the task rather than select responses that are opmal. We examined 3 large datasets from U.S. respondents– each had a series of rangs to complete on a single screen within web-based surveys. All quesonswere presented in a grid structure (elements in the rows, responses in the columns) where non-differenaonappears to be most likely to occur. First, across studies, non-differenators ranged from lows of 1% to 7.5%.With regard to means and top 2 box scores, in two studies means did not differ significantly with or withoutnon-differenators, though there was a very small effect for top 2 box scores...2.23.2 Deviaons from Standardized Interviews: An Analysis of Survey Pracces in the German MicrocensusG. Güllner 2 , J. Blasius 2 , S. Köhne-Finster 11 Federal Stascal Office Germany, Germany; 2 University of Bonn, GermanyThe objecve of standardized interviewing is to create uniform condions for all respondents. Only if thecontext of data collecon is standardized and only in case that the smuli are the same across respondents,high data validity can be achieved and comparable data can be collected. The interviewer is thus required toask the survey quesons exactly as they were phrased by the researcher. Among others, they have to read outboth all quesons and all response categories to the respondents without changing formulaons. In pracce,many interviewers seem to violate interviewing rules in pracce, potenally causing data distorons which canhardly be corrected ex post.2.23.3 The research on the mobility of tourists in Sicily: detecon and esmaon of non-sampling errorsA. Oliveri 1 , A. Parroco 11 Università degli Studi di Palermo, ItalyIt is well known that in all research fields non-sampling errors affect the interpretaon of results in oen dramacterms, especially when large samples are drawn. This is also the case of the research on the mobilityof tourists in Sicily, where in years 2009-2010 almost 4000 valid interviews were obtained in the context of a
