Teaching statistics to students in our area of economics and educational science often brings about the problem that students have either forgottentheir statistical knowledge, or have taken different classes than the ones we offer in basic statistics. We therefore need some kind of statistical...

E-learning plays an important role in education as it supports online teaching via computer networks and provides educational services by utilising information technologies. This paper presents a case study describing the development of an Arabic language e-learning course in statistics. Under...

Since the age of Gutenberg, publishing has meant to print a book readable by a person. Of course, interaction and dynamic illustration were not possible with this media. Even during the electronic age (till the mid of the nineties), publishing had not changed much. Although media, like diskettes...

Statistical software has also become an important part of scientific research that is reflected in the publications of the research results. Publishing a mathematical theorem requires also the publication of the proof of this theorem. The result of a computation can be seen as the equivalent of...

Students of introductory courses consider statistics as particularly difficult, as the understanding of the underlying concepts may require more time and energy than for other disciplines. For decades statisticians have tried to enhance understanding with the help of technical solutions such as...

Modern statistical computing requires smooth integration of new algorithms and quantitative analysis results in all sorts of platforms such as webbrowsers, standard and proprietary application software. Common statistical software packages can often not be adapted to integrate into new...

A statistical user interface is an interface between a human user and a statistical software package. Whenever we use a statistical software package we want to solve a specific statistical problem. But very often at first it is necessary to learn specific things about the software package....

In der Vergangenheit wurden viele (interaktive) Lehrmaterialien auf proprietären Plattformen entwickelt. Mit den Web 2.0 Technologien bieten sich neue interaktive und technische Möglichkeiten der Darstellung dieser Lehrinhalte auf einer standardisierten Plattform an. Existierende und neue...

Exploratory factor analysis (EFA) is an important tool in data analyses, particularly in social science. Usually four steps are carried out which contain a large number of options. One important option is the number of factors and the association of variables with a factor. Our tools aim to...
