Description:
This site, designed by Gerard E. Dallal of Tufts University, describes what to do with data sets instead of simply presenting theory and methods as they appear in standard textbooks. The site emphasizes statistical practices such as: foundation of statistics, the basics of statistics, confidence intervals, tests of significance, sample size calculation, single linear regression, multiple linear regression and analysis of variance. This is fairly comprehensive look at different aspects of this field.
