I just made that statistic up. What is not made up however is that many of us feel nervous and confused when confronted by statistics and those states are heightened if we are required to explain statistics. Fear not, the re are plenty of knowledgeable statisticians out there to help those of us who are statistically challenged.
The site Hyperstat Online Statistics Textbook is one such resource. It is a long running blog resource curated by David Lane, who is an Associate Professor of Psychology, Statistics, and Management at Rice University in Houston, Texas.
