PHStat2 version 2.8

Basic Business Statistics, 11th edition, first published in March, 2008, is the first book to include PHStat2 version 2.8. This version adds a separate-variance t test and a c chart procedure and replaces the Tukey-Kramer Procedure with a new One-Way ANOVA procedure that contains a Tukey-Kramer output option. Version 2.8 also includes the McNemar Test procedure that was new to version 2.7. There is a free update to version 2.8.1 available here for early copies of version 2.8.

Version 2.8 is not currently available for separate purchase, but version 2.7 remains available for separate purchase at mypearsonstore.com and other online retailers.
