Does the mere mention of the phrase “sampling distributions” bring a tingle to your spine? Visitors to this site will fear this basic concept of statistics (along with many others) no longer, as it does a fine job of explaining them in a fashion that is both lucid and jargon-free. Created and maintained by Professor David M. Lane of Rice University, the HyperStat Online site contains an online introductory statistics textbook, complete with sections on normal distributions, confidence intervals, prediction, and the logic of hypothesis testing. Each section contains a number of discrete subsections, and users can feel free to browse around at their leisure. Professor Lane has also included a number of external links to related resources, including a visual statistics site by David Krus of Arizona State University and a “Stat Primer”, authored by Bud Gerstman of San Jose State University. Overall, this site is tremendously helpful, and will be of great assistance to those entering the world of statistics for the first time. [KMG]
