In their own words
IBM SPSS Statistics
IBM SPSS Statistics is desktop software for statistical analysis, data preparation, predictive modeling, forecasting, and automated analysis. Its methods include statistical testing, regression, mediation analysis, multivariate time-series analysis, bootstrapping, decision trees, neural networks, and complex-sample analysis. The AI Output Assistant, powered by watsonx.ai, analyzes selected results and presents plain-language insights. Python and R plug-ins let users work with those languages inside SPSS Statistics. IBM lists subscription, perpetual, campus, and student licenses. The Base subscription is $99 a month per authorized user and includes Statistics Base, data preparation, and bootstrapping. Three other named subscriptions are each $79 a month, with features for custom tables and advanced statistics, forecasting and decision trees, or complex sampling and testing. A 14-day trial requires no credit card to create an account, and there is no free plan. IBM says the desktop software is not supported on Linux; an authorized-user license also cannot run remotely through multi-session environments.
