Teaching statistics to students in our area of economics and educationalscience often brings about the problem that students have either forgottentheir statistical knowledge, or have taken different classes than the ones weoffer in basic statistics. We therefore need some kind of statistical dictionarywhere we, as teachers, can refer to a common base and where students canlook up specific terms. The Wikipedia - a general online encyclopaedia -compelled us to use a wiki for our dictionary. While the Wikipedia containsa large number of statistical terms, these are often too long and detailed tobe visual displayed in lectures very well and some more specific terms arenot included.
