Plus, you can also save or export analysis result datasheet in PDF, Excel, RTF, CSV, and Text formats.

Note: This software takes considerably longer time to load data files when compared to other software. Occasionally, it also freezes while loading the data.

PSPP

PSPP is one more free statistical analysis software for Windows. This software is created as a replacement for the proprietary program SPSS. Almost all features and way of operation of this software is quite similar to SPSS with some minor exceptions like no Time bombs i.e. your copy of PSPP will not expire in future due to some time limitation.

In this analysis software, you can perform various operations like Linear and logistic regression, Descriptive statistics, T-tests, Measures of association, Cluster analysis, Reliability and factor analysis, Non-parametric tests, and more. Plus, you can also plot Graphs (Histogram, Scatterplot, and Bargraph) using variables of input files. In this software, you can open and analyze data of mainly Data and Syntax files. Besides these formats, you can also open data of other file formats like TXT, HTML, ODT, etc., but you cannot perform analysis, and other operations on them.

This software is not only used to analyze statistics, but you can also create your own data sequence by manually entering the data in the newely created file. All the data is filled in a spreadsheet-style interface.

On the main interface, you can view the data in two categories namely Data View and Variable View by selecting the respective field. To make statistical analyzing easy, this freeware provides a dedicated Analyze Tab that contains all important analyzing tools like Descriptive Statistics, Compare means, Univariate Analysis, Regression, etc. Besides this tab, some other useful Tabs like Transform (to compute data, to count occurrences of values, to rank cases, etc.), Data (to perform sorting, transpose, aggregate, etc. operation), etc. are also available.

After analysis, you can save the final result and graph as PDF, HTML, ODT, TXT, PS, and as CSV file format.

Spread gives you an Excel-type spreadsheet which contains all the data in rows and columns, that you can analyze using various statistical procedures including parametric, non-parametric tests, and multivariate analysis. Plus, the spreadsheet interface also supports calculations with cell formulae. In figure Window, you can simply draw schemes, create graphs, and also present them as a slideshow. The interface of this software also supports multiple windows that enable you to open and analyze multiple data files of various formats (Excel, Text, and Kyplot) at a time.

To perform statistical analysis, it comes with a dedicated Statistics drop-down menu. This Statistics menu contains various tests and analysis techniques such as Descriptive analysis, Contingency table, Parametric Test, Regression Analysis, Multivariate Analysis, and more. Performing statistical analysis in this software is not very difficult as you just need to select data entries from the table and then use one of the available analysis methods to get the result. I find only one problem with this freeware is that the result of analysis overwrites a part of the table. After the analysis, you can save the spreadsheet or table as CSV, XLS, TXT, PRN, HTML, etc. files.

Along with Statistics menu, you can use few more handy menus like Math (to perform matrix operation, Fourier transform, time series analysis, etc.), Graph (to create pie graph, bar graph, mech graph using table data), etc.
