SPSS is a proprietary commercial statistical software package. It enables statisticians and researchers to perform complex data analysis operations.

Even though SPSS is powerful, it has some issues. It's costly, so small groups or solo researchers might find it hard to afford. Also, its interface isn't as user-friendly as other stats software. Finally, while many people use SPSS, it isn't as flexible as free alternatives for customizing.

The same goes for Mathematica, which is an advanced modern technical computing system spanning all areas of technical computing—including, statistics, data analysis, neural networks, machine learning, image processing, geometry, data science, visualizations, and others.
