This site aims "to provide free, high quality, interactive, web-based resources for students and teachers of probability and statistics" It covers probability, statistics and "special models" such as finite sampling models and the Poisson process - they are presented here with text and interactive Java tutorials. Each page suggests mathematical exercises and simulation exercises, with some external links. The site requires the Mozilla Firefox browser (version 1.5 or later), with the MathML fonts installed, and with the Java plug-in (version 1.5 or later).
Interactive Tutorials in Statistics for Economists
This is a complete Java-based tutorial in introductory statistics, which can be used online or downloaded for offline use. It exposes the students to many data sets and uses interactive graphs which the student can alter by sliding controls. You must register to use this site.
This is an open online course, available freely to independent learners but with a fee for students who want feedback from an instructor. The course makes much use of online text, diagrams and interactive assignments. It is comprised of four units: Exploratory Data Analysis, Producing Data, Probability and Inference. These are subdivided into a total of twelve modules and more than two hundred "pages" of material. It is similar to the companion course on Statistical Reasoning, but with a more classical treatment of probability.
An interactive tutorial combining graphs, text and interactive features. Twenty-five units cover topics from rounding and central tendency up to regression lines and Chi squared tests
