IBM SPSS is commercially available, copyrighted software, and is not available for free. As a student or staff member, you may have access to SPSS via your university at no cost to you. If that is not an option, then sites such as On The Hub (https://onthehub.com/) are authorized vendors for very inexpensive, student (or faculty) leases for 6- or 12-month periods.
There is a "work-alike" package, PSPP, that includes many of the capabilities of the base SPSS package, including using the same data file formats, that is available for free: https://www.gnu.org/software/pspp/
As well, the R package is the fastest growing, user-supported statistical freeware system, with new libraries of specific statistical routines being added monthly: https://www.r-project.org/
Finally, here are two sites that list a lot of free (or free to try) statistical/analytic software that may be of interest:

Yes, its true that IBM SPSS is copyrighted software, and from any website, it is not available for free. However, you can download it from your university website (if available).
There is an open sourced clone of SPSS called PSPP as mentioned by @Sheikh Mohammad Famim Ahmed . The data files, and scripts are cross compatible. Comparatively small in size. Its a free download(Size under 100 MB). The output graphs are not that customiziable and nice as SPSS. Worth trying it if you can not afford SPSS licence. Supports imorts of spread sheets and some data formats .
No wide support as SPSS for many data file formats. Multi platform compatible - Has Linux/Mac versions(Inter platform portability ).Faster than SPSS . Maximum variables same as SPSS, Supports for More than 1 billion cases (SPSS 2.15 billion)
