Summary: We investigate the reasoning of preservice teachers about uncertainty in the context of randomization tests. Last winter term (2011/2012), we developed a seminar about data analysis with TinkerPlots, where group comparisons have played a fundamental role. A typical task in this context was: ``Is there a difference between two groups or could that difference have occurred at random due to the selection of our sample?" In the first part of this article we describe a possible method to answer such a question with the help of a randomization test facilitated with TinkerPlots. In the second part we point out how the participants of our course conducted a randomization test in a statistical project work and which problems and (mis-)conceptions were observed.
