In Introduction to PSPP, a Step by Step, Dr. Elizabeth Bigham guides the reader through the steps of basic statistical analysis commonly used in social science research using PSPP, a statistical analysis software program currently available for no charge through GNU (GNU.org). The text begins with a review of the steps of preparing data for analysis, followed by guidance through manipulating the variables. Each step of conducting descriptive statistics is explained and then the reader is guided through the steps of determining which analysis to run to test their hypotheses. The remaining chapters provide instructions for several types of inferential statistical analyses, including correlations, t tests, ANOVAs, etc. Introduction to PSPP is loaded with practical tips and examples to help the reader connect the material to real life examples. It also includes a data set so the reader can follow along, conducting the analyses in the examples for practice. This text is a must have tool for undergraduate, or graduate, students who want to use PSPP for analysis in social science research.
