LSP 121 Activity 2 Introduction to Statistics and SPSS (PASW) Introduction SPSS (Statistics Package for the Social Sciences) which in its latest version was renamed PASW is a software package used for conducting statistical analyses, manipulating data, and generating tables and graphs that summarize data. Statistical analyses include basic descriptive statistics, such as averages and frequencies, to advanced inferential statistics, such as regression, analysis of variance, and factor analysis. PASW for Windows consists of five different windows, each of which is associated with a particular PASW file type. We will examine two of these windows: the Data Editor and the Output Viewer. The Data Editor The Data Editor window displays the contents of the working dataset. It is arranged in a spreadsheet format that contains variables in columns and cases in rows. Notice how there are two tabs at the bottom of the window: Data View, and Variable View. The Data View tab lets you examine the data, much like it appears in an Excel spreadsheet. The Variable View tab allows you to examine information about the dataset that is stored with the dataset. 1

To import an Excel spreadsheet into PASW/SPSS, perform the following: Copy the file AgeAtInauguration.xls (from the QRC website) to the folder C:\My Documents. Then, go to Start -> Courseware Applications -> Statistical Applications -> PASW for Windows -> PASW 18.0 (or whatever the latest version is) for Windows. (Note: Depending on which lab you are in, PASW/SPSS may be in a different location. Check with your instructor.) Then wait for PASW to load. This could take several seconds. In PASW, click on File / Open / Data, and select your file C:\My Documents\AgeAtInauguration.xls. (You may have to change “Files of type:” to either Excel or All Files. Then select Sheet1.) Once the data is loaded, click on the Variable View tab near the bottom of the screen. Do you have a variable named V3? If so, you need to change its type to numeric . You could even rename V3 and the other variables to more useful variable names. Once this is done, click on the Data View tab near the bottom of the screen. PASW doesn’t always like Excel labels.
