SPSS has a one-time package and subscription plans, aside from the free trial.
You will need to log into the SPSS software with your IBMid. The trial gives you access to the entire suite of features for 30 days. The SPSS package is available for Apple Mac and Microsoft Windows PC operating systems.
While SPSS is not free to use, the SPSS offers a free trial before you buy. While the actual name is now IBM SPSS Statistics, the functions of the software remain largely unchanged. SPSS expanded into a variety of fields that went beyond the social sciences, especially after the IBM acquisition. SPSS was originally made for researchers in the social sciences like sociology, psychology, and additional services. While the letters in SPSS used to stand for Statistical Package for the Social Sciences, now the name is only an acronym.
