Quantitative methods have become a cornerstone of social science research. Consequently, they now also figure prominently in the quest of analysing democratic innovations. This chapter is to provide a glance at the potentials and pitfalls of using recent methodologies for evaluating such. One of the fundamental ideas behind democratic innovations is enriching aggregative models of democracy with discursive elements. We, hence, focus on the analysis of deliberative arrangements, as they are emblematic for discursive models of democracy. The chapter is divided in two major parts: measurement methods and evaluation methods. In the first part, we focus on different empirical instruments to operationalize and assess deliberation within democratic innovations. In the second part, we survey and review the most prominent techniques for evaluating the data generated by those instruments. Finally, we summarize the challenges and desiderata involved with quantitative methods in democratic innovation research.
