Conducting a Nonparametric Independent Samples ttest is Chapter 6 of Calculating Basic Statistical Procedures in SPSS: A SelfHelp and Practical Guide to Preparing Theses, Dissertations, and Manuscripts, authored by John R. Slate and Ana RojasLeBouef from Sam Houston State University. This book is written to assist graduate students and faculty members, as well as undergraduate students, in their use of the Statistical Package of the Social SciencesPC (SPSSPC) versions 1519. Specifically, we have generated a set of steps and screenshots to depict each important step in conducting basic statistical analyses. We believe that this book supplements existing statistical texts in which readers are informed about the statistical underpinnings of basic statistical procedures and in which definitions of terms are provided. Accordingly, other than providing a few basic definitions, we assume that dissertation chairs/thesis directors, students, and/or faculty will obtain their own definition of terms. We hope you find this set of steps and screenshots to be helpful as you use SPSSPC in conducting basic statistical analyses.
