CHAPTER 2 USING SPSS IN SOCIAL RESEARCH Chapter Objectives The objectives of this chapter are: 1. understanding SPSS and its various functions in the analysis of collected data; 2. learning how to transmit data from questionnaires and other forms of data collection to SPSS for analysis through data entry; 3. interpreting output from SPSS-generated information; 4. understanding the limitations of software packages such as SPSS; 5. understanding that human intervention in the data analysis process is both a necessary and integral part of the research process; and 6. understanding various myths about data analysis software programs. Chapter Summary Several software programs exist to enable researchers to analyze their data quickly and easily with some elementary computer programming. One of the more popular software programs for analyzing criminological data is SPSS, or the Statistical Package for the Social Sciences. SPSS is selected here because it has such wide application. Furthermore, it contains numerous tests, graphic programs, and correlation procedures of use to criminologists who do basic research. It is assumed that most students taking this course have had a basic research methods course and are acquainted with the fundamentals of data gathering, coding of questionnaire or interview information, and other mechanics associated with doing elementary research. SPSS software facilitates the data analysis process. This SPSS software is explained to a limited degree in the chapter. The intent is not to replace more extensive discussions of SPSS software published elsewhere. Rather, it is important for students to know that statistical packages and software programs exist to assist them in their research endeavors. The process of using SPSS begins with data entry, where researchers enter values for different variables taken from questionnaires and other research tools. Once data have been entered into the software program, a data set is established. From here, various tests, techniques, and graphic presentation may be performed with the data set to describe and make decisions about one's findings. SPSS has a base system, which includes most of the software most criminologists will ever need to analyze their data.

There are additional modules available through SPSS, Inc. that can perform specialized and more advanced tasks if needed. A brief description of branches of different options available to researchers was presented, showing that different windows when SPSS is opened allow for various choices concerning what researchers want to do. A investigator's research objectives guide this analysis process by indicating what tests ought to be conducted and what types of graphic presentation will best portray one's findings. Discussed were some of the major limitations of data analysis software. Software programs, such as SPSS, process numerical information. They do not interpret this information. Rather, it is imperative for investigators to do most of the interpretive work. Thus, merely generating numerical information, although useful, requires human intervention and guidance. Some investigators rely too heavily on software output in their research, and they do not apply a great deal of thought to the interpretive work they must perform in order to get the most from the data they have collected. There are also software program weaknesses, where data of different types are manipulated in ways so as to render the results meaningless or useless for any practical research purpose. Several myths associated with data analysis software programs were presented. It is imperative that investigators insinuate themselves into the data analysis process and make important interpretations of the data they have collected. Software programs such as SPSS cannot do everything for the researcher. Therefore, researchers must become familiar with different statistical procedures, their appropriate applications, and their weaknesses and strengths. Statistics is an art in some respects, and students must learn to distinguish between different tests and techniques that have similar purposes but quite different assumptions for their legitimate application.
