Single variable large sample (n > = 30)

Single variable small sample (n < 30)

Time series data for control chart about the mean or for P-Charts

Two independent data sets (large and small sample)

Paired data (dependent) appropriate for t-tests

Data pairs for simple linear regression

Data for multiple linear regression

Data for one-way ANOVA

Data for two-way ANOVA

Additional information and activities using these data sets are available in the Technology Guide (ISBN: 0-618-20557-8) and Excel Guide (ISBN: 0-618-20556-X) that accompany Understandable Statistics, 7e. The Technology Guide focuses on the TI-83Plus and Minitab (in addition to the software program ComputerStat) while the Excel Guide provides detailed information for Excel. All activities are correlated to topics covered in the student text. To purchase these Guides, visit Houghton Mifflin’s on-line bookstore.
