SPSS is a software package for statistical data analysis
SPSS stands for “Statistical Package for the Social Sciences”. It is a modular software package for statistical data analysis. The first version was developed by Norman H. Nie at Stanford University in 1968, and gave the company its name (SPSS Inc.). In 2009, IBM took over the SPSS Company. The software itself was called PASW at the time (Predictive Analysis SoftWare). The software package was greatly expanded over the years. IBM SPSS Statistics can be used on the Windows, Apple Macintosh and Linux computer platforms. IBM Germany now offers student versions of the software. With a wide range of analytical techniques, users can evaluate data to detect subtle relationships that could otherwise never be determined with a simple spreadsheet program. SPSS helps choose the right technology and capture the significance of the results.
SPSS offers users a variety of options
IBM SPSS statistics includes four program levels: data, syntax, output, script. These levels are each used as separate files. To secure all processing steps, all four levels must be stored separately. Each of these levels shows a normal menu bar at the top. Under edit/options, you can make many adjustments, as well as display and use various program levels.
Using SPSS offers users many advantages as opposed to a traditional spreadsheet program. For example, they save time by importing data with just a few clicks. The database wizard will guide you through the import and export of many different data sources such as spreadsheets and databases – without it the data would need to be changed or re-entered. Data can also be used without any limitations: in a conventional spreadsheet program the end is reached with one million rows of data, with IBM SPSS Statistics you can easily manage several million rows so that users no longer have to separate data and analyse it in fragments. In addition, costly errors can be prevented thanks to SPSS. Sorting errors often occur in worksheets. In IBM SPSS Statistics data sets are handled in databases where they are provided with IDs, which avoids duplicate records and sorting errors. To sort, users only need to right click and make their selection. Formula errors are also a thing of the past with SPSS. Functions in spreadsheet programs depend on the mathematical knowledge of the user. It can very quickly happen that formulas overwrite important data or incorrect formulas are created when entering them into rows or columns. With IBM SPSS Statistics you do not need to enter any formulas, and because the results are separated from the data in IBM SPSS Statistics, there is no risk of affecting the results when analysing data. Errors are automatically detected and localised. There is also another advantage: SPSS can easy generate recurring monthly reports or data analysis automatically and save it in your menu items. The report is updated with a single mouse click. There is another significant advantage: SPSS makes it easy to visually analyse data with more than 50 integrated chart types. The possibilities go far beyond traditional business charts with box plots, pie charts, stem leaf diagrams and many more. Users can create charts while adjusting work flow. You can also create tables within seconds because of the intuitive interface of the software with drag and drop.
