Textbook in PDF format SPSS software can read and write data from other statistical packages, databases, and spreadsheets. When entering data into the software, one has to click on "variable view." The variable view enables the user to customize it by data type and consists of the following headings: Name, Type, Width, Decimals, Label, Values, Missing, Columns, Align, and Measures. These headings enable the user to characterize the data. SPSS is most often used in social science fields such as psychology, where statistical techniques are involved at a large scale. In the field of psychology, techniques such as cross tabulation, t-test, chi square test, etc., are available in the "analyze" menu of the software. SPSS involves some sophisticated inferential and multivariate (ANOVA) statistical procedures such as factor analysis, discriminate analysis, analysis of variance, etc. SPSS, as the name suggests, is software for performing statistical procedures in the social sciences field. The major limitation of SPSS is that it cannot be used to analyze a very large data set. A researcher often gets a large data set in the field of medicine and nursing, so in those fields, the researcher generally uses SAS (Statistical Analysis System) instead of SPSS to analyze the clinical data.
