**SPSS Statistics** is a statistical software suite developed by IBM for data management, advanced analytics, multivariate analysis, business intelligence, and criminal investigation. Long produced by SPSS Inc., it was acquired by IBM in 2009. Versions of the software released since năm ngoái have the brand name **IBM SPSS Statistics**.

The software name originally stood for **Statistical Package for the Social Sciences** (**SPSS**),^{[3]} reflecting the original market, then later changed to lớn **Statistical Product and Service Solutions**.^{[4]}^{[5]}

## Overview[edit]

SPSS is a widely used program for statistical analysis in social science.^{[6]} It is also used by market researchers, health researchers, survey companies, government, education researchers, marketing organizations, data miners,^{[7]} and others. The original SPSS manual (Nie, Bent & Hull, 1970)^{[8]} has been described as one of "sociology's most influential books" for allowing ordinary researchers to lớn tự their own statistical analysis.^{[9]} In addition to lớn statistical analysis, data management (case selection, tệp tin reshaping and creating derived data) and data documentation (a metadata dictionary is stored in the datafile) are features of the base software.

The many features of SPSS Statistics are accessible via pull-down menus or can be programmed with a proprietary 4GL *command syntax language*. Command syntax programming has the benefits of reproducible output, simplifying repetitive tasks, and handling complex data manipulations and analyses. Additionally, some complex applications can only be programmed in syntax and are not accessible through the thực đơn structure. The pull-down thực đơn interface also generates command syntax: this can be displayed in the output, although the mặc định settings have to lớn be changed to lớn make the syntax visible to lớn the user. They can also be pasted into a syntax tệp tin using the "paste" button present in each thực đơn. Programs can be lập cập interactively or unattended, using the supplied Production Job Facility.

A "macro" language can be used to lớn write command language subroutines. A Python programmability extension can access the information in the data dictionary and data and dynamically build command syntax programs. This extension, introduced in SPSS 14, replaced the less functional SAX Basic "scripts" for most purposes, although SaxBasic remains available. In addition, the Python extension allows SPSS to lớn lập cập any of the statistics in the không lấy phí software package R. From version 14 onwards, SPSS can be driven externally by a Python or a VB.NET program using supplied "plug-ins". (From version trăng tròn onwards, these two scripting facilities, as well as many scripts, are included on the installation truyền thông media and are normally installed by mặc định.)

SPSS Statistics places constraints on internal tệp tin structure, data types, data processing, and matching files, which together considerably simplify programming. SPSS datasets have a two-dimensional table structure, where the rows typically represent cases (such as individuals or households) and the columns represent measurements (such as age, sex, or household income). Only two data types are defined: numeric and text (or "string"). All data processing occurs sequentially case-by-case through the tệp tin (dataset). Files can be matched one-to-one and one-to-many, but not many-to-many. In addition to lớn that cases-by-variables structure and processing, there is a separate Matrix session where one can process data as matrices using matrix and linear algebra operations.

The graphical user interface has two views which can be toggled. The 'Data View' shows a spreadsheet view of the cases (rows) and variables (columns). Unlike spreadsheets, the data cells can only contain numbers or text, and formulas cannot be stored in these cells. The 'Variable View' displays the metadata dictionary, where each row represents a variable and shows the variable name, variable label, value label(s), print width, measurement type, and a variety of other characteristics. Cells in both views can be manually edited, defining the tệp tin structure and allowing data entry without using command syntax. This may be sufficient for small datasets. Larger datasets such as statistical surveys are more often created in data entry software, or entered during computer-assisted personal interviewing, by scanning and using optical character recognition and optical mark recognition software, or by direct capture from online questionnaires. These datasets are then read into SPSS.

SPSS Statistics can read and write data from ASCII text files (including hierarchical files), other statistics packages, spreadsheets and databases. It can also read and write to lớn external relational database tables via ODBC and SQL.

Statistical output is to lớn a proprietary tệp tin format (*.spv tệp tin, supporting pivot tables) for which, in addition to lớn the in-package viewer, a stand-alone reader can be downloaded. The proprietary output can be exported to lớn text or Microsoft Word, PDF, Excel, and other formats. Alternatively, output can be captured as data (using the OMS command), as text, tab-delimited text, PDF, XLS, HTML, XML, SPSS dataset or a variety of graphic image formats (JPEG, PNG, BMP and EMF).

Several variants of SPSS Statistics exist. SPSS Statistics Gradpacks are highly discounted versions sold only to lớn students.^{[10]} SPSS Statistics Server is a version of the software with a client/server architecture. Add-on packages can enhance the base software with additional features (examples include **complex samples**, which can adjust for clustered and stratified samples, and **custom tables**, which can create publication-ready tables). SPSS Statistics is available under either an annual or a monthly subscription license.

Version 25 of SPSS Statistics launched on August 8, 2017. This added new and advanced statistics, such as random effects solution results (GENLINMIXED), robust standard errors (GLM/UNIANOVA), and profile plots with error bars within the Advanced Statistics and Custom Tables add-on. V25 also includes new Bayesian statistics capabilities, a method of statistical inference, and publication ready charts, such as powerful new charting capabilities, including new mặc định templates and the ability to lớn share with Microsoft Office applications.^{[11]}

SPSS was released in its first version in 1968 as the Statistical Package for the Social Sciences (SPSS) after being developed by Norman H. Nie, Dale H. Bent, and C. Hadlai Hull. Those principals incorporated as SPSS Inc. in 1975. Early versions of SPSS Statistics were written in Fortran and designed for batch processing on mainframes, including for example IBM and ICL versions, originally using punched cards for data and program input. A processing lập cập read a command tệp tin of SPSS commands and either a raw input tệp tin of fixed-format data with a single record type, or a 'getfile' of data saved by a previous lập cập. To save precious computer time an 'edit' lập cập could be done to lớn kiểm tra command syntax without analysing the data. From version 10 (SPSS-X) in 1983, data files could contain multiple record types.

Prior to lớn SPSS 16.0, different versions of SPSS were available for Windows, Mac OS X and Unix.

SPSS Statistics version 13.0 for Mac OS X was not compatible with Intel-based Macintosh computers, due to lớn the Rosetta emulation software causing errors in calculations. SPSS Statistics 15.0 for Windows needed a downloadable hotfix to lớn be installed in order to lớn be compatible with Windows Vista.

From version 16.0, the same version runs under Windows, Mac, and Linux. The graphical user interface is written in Java. The Mac OS version is provided as a Universal binary, making it fully compatible with both PowerPC and Intel-based Mac hardware.

SPSS Inc announced on July 28, 2009, that it was being acquired by IBM for US$1.2 billion.^{[18]} Because of a dispute about ownership of the name "SPSS", between 2009 and 2010, the product was referred to lớn as PASW (Predictive Analytics SoftWare).^{[19]} As of January 2010, it became "SPSS: An IBM Company". Complete transfer of business to lớn IBM was done by October 1, 2010. By that date, SPSS: An IBM Company ceased to lớn exist. IBM SPSS is now fully integrated into the IBM Corporation, and is one of the brands under IBM Software Group's Business Analytics Portfolio, together with IBM Algorithmics, IBM Cognos and IBM OpenPages.

Companion software in the "IBM SPSS" family are used for data mining and text analytics (IBM SPSS Modeler), realtime credit scoring services (IBM SPSS Collaboration and Deployment Services), and structural equation modeling (IBM SPSS Amos).

SPSS Data Collection and SPSS Dimensions were sold in năm ngoái to lớn UNICOM Systems, Inc., a division of UNICOM Global, and merged into the integrated software suite UNICOM Intelligence (survey design, survey deployment, data collection, data management and reporting).^{[20]}^{[21]}^{[22]}

### IDA (Interactive Data Analysis)[edit]

**IDA (Interactive Data Analysis)**^{[23]} was a software package that originated at what was formerly the National Opinion Research Center (NORC), at the University of Chicago. Initially offered on the HP-2000,^{[24]} somewhat later, under the ownership of SPSS, it was also available on DEC's DECSYSTEM-20.^{[25]} Regression analysis was one of *IDA*'s strong points.^{[24]}

### SCSS - Conversational / Columnar SPSS[edit]

**SCSS** was a software product intended for online use of IBM mainframes.
^{[26]}

Although the "C" was for **C**onversational, it also represented a distinction regarding how the data was stored: it used a **c**olumn-oriented rather kêu ca a row-oriented (internal) database.^{[citation needed]}

This gave good interactive response time for the SPSS Conversational Statistical System (SCSS), whose strong point, as with SPSS, was Cross-tabulation.^{[27]}

### Project NX[edit]

In October, 2020 IBM announced the start of an Early Access Program for the "New SPSS Statistics", codenamed **Project NX.**^{[28]}^{[29]} It contains "many of your favorite SPSS capabilities presented in a new easy to lớn use interface, with integrated guidance, multiple tabs, improved graphs and much more".

In December, 2021, IBM opened up the Early Access Program for the next generation of SPSS Statistics for more users and shared more visuals about it.^{[30]}^{[31]}
