20.500.12556/RUL-186649 Probability-based web panels for official statistics basic insights and analysis of the bias of survey estimates The past three decades of survey research have revealed a shift from traditional probability-based surveys to various types of web surveys. In official statistics, the probability-based web panels (PWPs), for which respondents are recruited once and then incentivized for repeated participation in web surveys, play a particularly important role in this process. This article provides insights into the use of PWPs for official statistics. First, a survey of European Union national statistics offices revealed that one-quarter had already implemented or were planning to implement PWPs; the main barriers to their implementation were lack of knowledge and expertise. In addition, we evaluated the quality of the estimates in the Slovenian PWP (1KA Panel) that replicated questions from 12 traditional probability-based surveys. The findings showed that 205 of 651 PWP estimates (31%) exhibited relative bias exceeding 10%. Biases varied substantially across survey topics, indicating the selective suitability of PWPs for official statistics. probability-based web panels survey estimates relative bias nonresponse error measurement error coverage error processing error official statistics spletni paneli na podlagi verjetnosti uradna statistika ocene anket relativna pristranskost napaka neodgovora napaka merjenja napaka pokritosti napaka obdelave true false true Angleški jezik Slovenski jezik Članek v reviji 2026-09-03 17:35:33 2026-09-03 17:35:36 2026-09-04 04:31:04 0000-00-00 00:00:00 2026 0 0 Str. 164–179 iss. 2 Vol. 106 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 311.213:004.738.5 0322-788X 10.54694/stat.2025.28 288484099 32019726q2_cehovin_vehovar.pdf 32019726q2_cehovin_vehovar.pdf 1 79047048F085E95C4E8598AF91C20B7B 6185a635b270253d7ade91caa1a99360a43307ddbd356d3387d079bca602cb3a 40bd6a1f-a7ad-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=245965 Fakulteta za družbene vede 0 0 0
