The scores in our dataset are not reality itself; they are glimpses at reality through the lens of the respective measurement instrument. In research practice, that distinction sometimes takes a backseat. However, if we want to combine numerical scores of different instruments, then the relationship between measurement and reality becomes …
This month we delve into an important but difficult matter in harmonization in general and ex-post harmonization in particular: How can we determine if two instruments measure the same concept? This is especially hard if the concepts are latent (i.e., not directly observable). Diesen Monat beschäftigen wir uns mit einem …
Post 1 in the series “Adventures in ex-post harmonization” Ex-post harmonization – combining data from different surveys – requires quite some effort. In this post, we explore the many reasons why it is still worth it. All benefits discussed here apply equally to large scale and smaller ex-post harmonization efforts. …
A blog post series on harmonizing data from different surveys. In this series of blog posts, we will explore ex-post harmonization: the art of combining data from different surveys. In this introductory post, I explain the motivation behind the series and outline the upcoming topics. The series is aimed at …
Was zeichnet ein exzellentes Forschungsdatenmanagement in der empirischen Bildungsforschung aus? Eine adäquate Dokumentation, eine rechtssichere Datenerhebung und –verarbeitung, eine hohe Datenqualität, die Nachvollziehbarkeit der Datengenese oder die Bereitstellung der Daten zur Nachnutzung durch Dritte? What distinguishes excellent research data management in empirical educational research? Adequate documentation, legally compliant data collection …
Dr. Sebastian Netscher clarifies the difference between Open Data and FAIR Data, and explains why even access-restricted data can conform to FAIR principles. He recommends that researchers focus on processing shareable data and rely on the existing research infrastructure of data archives and repositories. Dr. Sebastian Netscher erklärt den Unterschied …
