Greater integration of statistical software: Software output shown now uses R and Stata instead of only SAS and SPSS. The appendix provides instructions about basic use.
New examples and exercises ask students to use applets to help learn the fundamental concepts of sampling distributions, confidence intervals, and significance tests. The text also now relies more on applets for finding tail probabilities from distributions such as the normal, t, and chi-squared.
ANOVA coverage has been reorganised to put more emphasis on using regression models with dummy variables to handle categorical explanatory variables.
