SPSS is a proprietary statistical analysis software acquired by IBM in 2009. It offers statisticians, researchers, and students with advanced statistical analysis functions integrated within the program. SPSS also provides seamless integration with big data.
SPSS is not free and it's not cheap, though it does not work well on Linux systems as it does on Windows, so here we will provide a list of open-source free SPSS alternatives.
Free statistical analysis packages
JASP is considered one of the strongest competitors for SPSS, It has a user-friendly interface, supports many data formats, and provides Frequentist and Bayesian analysis.
JASP is available for Windows, Linux (Debian, Ubuntu, Fedora, RedHat, and any distro that supports Flatpak) and macOS (Sierra and later). JASP is also available to run in within the web browser by using rollApp platform but with limited features.
Supported file formats for JASP: .sav, .txt, .csv, .ods, and of course the .jasp format.
Jamovi is a free lightweight statistical analysis package, it comes with seamless integration with the R language and complete spreadsheet editing options. Jamovi is another open-source alternative for SPSS but with a fancy easy-to-use interface and smooth learning curve for students and beginners.
Jamovi offers installable executable packages for Windows, macOS, Linux (flatpak package), and ChromeOS (flatpak package).

Supported file formats: Excel files, tab-separated values (TSV), comma-separated values (CSV), Gnumeric and Open Document worksheets (OpenOffice/ LibreOffice files) and SPSS files.
R programming language is an open-source scripting environment for statistical computing and analysis. It's widely used by data scientists, data engineers, data miners, and statisticians. Here we are listing some open source projects that provide R with graphical user-interface, editors & IDE functionalities.
RStudio is a free IDE (integrated development environment) for R. RStudio is shipped with many features to provide the productive workflow, like a package manager, history manager, logger, customizable user-interface, scripts manager, auto-complete functions, code editor, code highlighting, file browser and built-in session manager.

Deducer is a lightweight open-source GUI (Graphical User Interface) for the R language, that works for Windows, macOS & Linux.
It's an easy-to-use alternative to SPSS, and it's easy to learn as well. In the following video you can watch an introductory tour of Deducer
11- Rodeo (Python Statistical Analysis IDE)
Rodeo is an open-source statistical IDE for Python language. It's the RStudio equivalent for Python statistical libraries, and capabilities. It has a similar interface to RSudio and similar functionalities as well. However, it has not been updated for 3 years.
Rodeo supports Windows, Linux, and macOS.
12 - Juno IDE (Julia language IDE)
Julia is an open-source high-level general-purpose programming language. However, it comes with features that put it ahead in statistical & mathematical analysis. Juno IDE is an Atom-based IDE for Julia language, it combines the Atom IDE features with a data analysis aware user-interface very similar to RStudio and Rodeo.
The Julia programming language has many data-science ready packages including data manipulation, mathematics, and BigData ready packages. It supports also using packages from Python, R, C/Fortran, C++, and Java.
