SPSS Basic 1: Public Opinion and Attitude
Keywords: SPSS, variable properties, subset, descriptive statistics, cross-table, regression, scatter plot.
SPSS is statistical analysis package that first released in 1968. For years, SPSS is among the most widely used programs for statistical analysis in social science. It is used by market researchers, health researchers, survey companies, government, education researchers, marketing organizations and others. The Social Science Data Services at Government Information department designs the SPSS workshop series to introduce this application, and several primary social science data resources will also be presented.
In the first workshop, Public Opinion and Attitude, you will explore the data from General Social Survey (also available to Northwestern affiliates from Roper Center) in SPSS to test if there are statistical differences on attitudes towards some key issues across different groups. You will learn how to use SPSS 18 to:
- Load in a data file in various formats, including SPSS, Stata and Excel spreadsheet.
- Manage and organize the data file, generate new variables, create subsets.
- Run descriptive statistics (average, range, count, etc), generate cross-tables, and visualize the result by bar graph and pie graph.
- Run linear regression and visualize using scatter plot.
We will also include the introduction on categories of numerical information and variables. Although we will present the Syntax file and Output file, this workshop will be "point and click" in various windows without much programming. At the end of the workshop, we will introduce Roper Center, one of the key resources for public opinion polls.
