Note to the instructor: The data set used in this exercise is g96asp.por which is a subset of the 1996, General Social Survey. (Some of the variables in the GSS have been recoded to make them easier to use and some new variables have been created.) This exercise focuses on comparing means using ttests and one way analysis or variance. The exercises were written to accompany SPSS for Windows Version 7.5: A Basic Tutorial, by Richard Shaffer, Edward Nelson, Nan Chico, John Korey, Elizabeth Nelson, and Jim Ross. The ISBN is 007366023X. There is a version of this book (with accompanying data disk) currently available for SPSS 6. To order this book, call McGrawHill at 18003383987. The ISBN is 0079136737.
