Hadlai Hull Initial release 1968; 52 years ago ( 1968 ) Stable release 27.0. Current versions (post 2015) have the brand name: IBM SPSS Statistics. The original SPSS manual (Nie, Bent Hull, 1970) 6 has been described as one of sociologys most influential books for allowing ordinary researchers to do their own statistical analysis. In addition to statistical analysis, data management (case selection, file reshaping, creating derived data) and data documentation (a metadata dictionary is stored in the datafile ) are features of the base software. 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 menu structure. The pull-down menu interface also generates command syntax: this can be displayed in the output, although the default settings have to be changed to make the syntax visible to the user. They can also be pasted into a syntax file using the paste button present in each menu. Programs can be run interactively or unattended, using the supplied Production Job Facility. A Python programmability extension can access the information in the data dictionary and data and dynamically build command syntax programs. The Python programmability extension, introduced in SPSS 14, replaced the less functional SAX Basic scripts for most purposes, although SaxBasic remains available. Spss Statistics Software Free Software PackageIn addition, the Python extension allows SPSS to run any of the statistics in the free 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 20 onwards, these two scripting facilities, as well as many scripts, are included on the installation media and are normally installed by default.). Only two data types are defined: numeric and text (or string). Files can be matched one-to-one and one-to-many, but not many-to-many. In addition to 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. 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 file structure and allowing data entry without using command syntax. 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. SPSS Statistics can read and write to external relational database tables via ODBC and SQL. The proprietary output can be exported to 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 ).
