Social media platforms act as the gatekeepers for research data, as they regulate the access to data generated by and used within the platform. Twitter has been probably one of the most research/academia friendly social media-platform which is evident from the high number of publications based on Twitter data. This …
This blog post discusses a recent large-scale Twitter dataset and its potential applications in research. The dataset consists of over 375 million tweets collected over 24 hours in 2022 by 80 scholars. The data provides a valuable reference point for future research projects and presents exciting research opportunities, including examining …
Mit Verbreitung des Corona-Virus sind etliche Studien und Projekte entstanden, die die Auswirkungen der COVID-19-Pandemie und ihrer Bekämpfung auf die Gesellschaft empirisch erfassen. Die Spannbreite ist groß und reicht von Momentaufnahmen in Befragungen mit selbstselektierten Stichproben, repräsentativ angelegten Surveys, Corona-Tagebüchern bis hin zur Aufnahme in Langzeitstudien. Der RatSWD hat von …
In the finale of season 1 of the blog series, I explore the idea to craft control variables that help us mitigate quality and comparability issues in our source surveys. Embedding such control variables into our ex-post harmonized datasets creates a living documentation of our source material and our harmonization …
This time, we apply multiple imputation to harmonize data for the same construct measured different instruments. We will treat data as swiss cheese and then unleash mice, sorry MICE, on it. The approach will pose some hurdles regarding the required data and the analysis complexity. However, if those hurdles are …
Equipercentile equating is an alternative version of observed score equating that can accommodate non-normal response distributions. It corrects for differences in mean and standard deviation but also higher distribution moments, such as skewness and kurtosis. This helps harmonize instruments, where, for example, respondents mostly choose high (or low) response options. …
