SPSS Statistics is a software package that is used for logical statistical analysis in batch and not in batch. Long produced by SPSS Inc., it was purchased by IBM in 2009. Current versions (2015) are officially named IBM SPSS Statistics. Complementary products from the same family are used for the creation and implementation of surveys (IBM SPSS Data Collection), data mining (IBM SPSS Modeler), text analysis, collaboration and implementation (automated services and batch scoring). The name of the software originally meant statistical package for social sciences (SPSS), which reflects the original market, although the software is now also popular in other fields, including health sciences and marketing.

SPSS overview


SPSS is a widely used program for statistical analysis in the social sciences. It is also used by market researchers, health researchers, survey companies, government, education researchers, marketing organizations, data miners and others. The original SPSS manual (Nie, Bent & Hull, 1970) has been described as one of the "most influential books in sociology" to allow ordinary researchers to perform their own statistical analyses. In addition to statistical analysis, data management (case selection, file remodeling, derivative data creation) and data documentation (a metadata dictionary has been stored in the data file) are features of the basic software.


Statistics included in the basic software:


Descriptive statistics: cross-tabulation, frequencies, description, exploration, descriptive proportion statistics
Bivariate statistics: averages, t-tests, ANOVA, correlations (bivariate, partial, distances), non-parametric tests
Forecast for numerical results: linear regression
Forecast to identify groups: factorial analysis, cluster analysis (two steps, K-media, hierarchical), discriminating
