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.
