Forschung
Saskia Bartholomäus ist Doktorandin in der Abteilung Data and Research on Society bei GESIS - Leibniz-Institut für Sozialwissenschaften. Ihr aktueller Forschungsschwerpunkt ist die Datenqualität sozial- und politikwissenschaftlicher Umfragen. In ihrer Dissertation untersucht sie den Non-Response und Attrition Bias von Nichtwählenden in politikwissenschaftlichen Umfragen, die daraus resultierenden Limitationen inhaltlicher Forschung und potentielle Lösungsmöglichkeiten. Dabei beschäftigt sie sich neben Adaptive Survey Designs mit Imputations- und Gewichtungsstrategien, um Selection Biases in politikwissenschaftlichen Umfragen zu reduzieren.Veröffentlichungen
