The Student Data CD, which is packaged with every new copy of the text, contains files for all of the data sets in the text that are marked by a CD icon. These include data sets for text examples, exercises, and “Statistics in Action” cases. All data files are saved in four different formats: MINITAB, SAS, SPSS, and ASCII (for easy importing into other statistical software packages). The CD also contains the applets used to illustrate statistical concepts.
