The software environment R is widely used for data analysis and data visualization in the social sciences and beyond. Additionally, it is becoming increasingly popular as a tool for data and file management. Focusing on these latter aspects, this Methods Bites Tutorial by Marcel Neunhoeffer, Oliver Rittmann and our team members Denis Cohen and Cosima Meyer illustrates the workflow and best practices for efficient data management in R.

Whether researchers occasionally turn to Bayesian statistical methods out of convenience or whether they firmly subscribe to the Bayesian paradigm for philosophical reasons: The use of Bayesian statistics in the social sciences is becoming increasingly widespread. However, seemingly high entry costs still keep many applied researchers from embracing Bayesian methods. Next to a lack of familiarity with the underlying conceptual foundations, the need to implement statistical models using specific programming languages remains one of the biggest hurdles. In this Methods Bites Tutorial, Denis Cohen provides an applied introduction to Stan, a platform for statistical modeling and Bayesian statistical inference. Continue reading
Shiny Apps allow developers and researchers to easily build interactive web applications within the environment of the statistical software R. Using these apps, R users can interactively communicate their work to a broader audience. In this Method Bites Tutorial, Konstantin Gavras and Nick Baumann present a comprehensive recap of Konstantin Gavras’ (University of Mannheim) workshop materials to illustrate how Shiny Apps enable vivid data presentation as well as its usefulness as an analytical tool.

The online encyclopedia Wikipedia, together with its sibling, the collaboratively edited knowledge base Wikidata, provides incredibly rich yet largely untapped sources for political research. In this Methods Bites Tutorial, Denis Cohen and Nick Baumann offer a hands-on recap of Simon Munzert’s (Hertie School of Governance) workshop materials to show how these platforms can inform research on public attention dynamics, policies, political and other events, political elites, and parties, among other things.

How can we infer actors’ positions, substantive topics, or sentiments from (political) texts? This Methods Bites Tutorial by Julian Bernauer summarizes Denise Traber’s workshop in the MZES Social Science Data Lab in Spring 2018. Using exemplary sets of political documents (election manifestos and coalition agreements), it showcases tools of QTA for a variety of analytical objectives and demonstrates how to create, process, and analyse a text corpus through a series of hands-on applications.

How do you access Twitter’s API, collect a stream of tweets, and analyze the retrieved data? Which potentials, challenges, and limitations for social scientific research come along with using Twitter data? This Methods Bites Tutorial by Denis Cohen, based on a workshop by Simon Kühne (Bielefeld University) in the MZES Social Science Data Lab in Spring 2019, aims to tackle these questions.
