PSPP
PSPP is a statistical analysis application for working with sampled data, running common tests, and producing tables and charts.
What is PSPP?
PSPP is a statistical analysis application that helps users work with sampled data through both a graphical interface and command-driven workflows. It is commonly used by students, researchers, and analysts who need an accessible desktop tool for descriptive statistics and standard hypothesis testing. The app supports procedures such as t-tests, ANOVA, regression, nonparametric tests, factor analysis, and reliability analysis, making it useful for coursework, survey analysis, and general research tasks. PSPP can also produce tables and charts and export output in multiple formats for reporting and review. On Mac, users may encounter PSPP as a native desktop app or as a command-line tool in research and academic workflows. It is published as part of the GNU Project.

Safety overview
Status: Safe
PSPP is legitimate statistical software used for data analysis. It typically accesses the files and datasets you choose to open or save, which is normal for this kind of desktop application. If you use it with sensitive research or survey data, store those files in locations you trust and review exported reports before sharing them.
Recommendation: Keep PSPP if you use it for coursework, research, or data analysis. If you no longer need it, you can remove the app, but save any datasets, syntax files, or exported reports you want to keep first.
