IBM made SPSS Statistics 31 available on 10 June 2025. The release introduced additional tools for exploring relationships in research and business data.
New analytical options
Proximity mapping provides spatial representations of relationships among objects in multivariate datasets. Distance correlation helps investigate statistical dependence, including relationships that are not simply linear.
IBM's release notes also document compatibility issues and installation guidance. Before upgrading, users should review those notes and confirm that their operating system and any R or Python integrations meet the release requirements.
