I would like to purchase SPSS but do not have a student email. Any solution for that?

You should have a student email.

Visit this site - https://studentdiscounts.com/?adoper=174258_1_OT2 and purchase the standard pack  which includes advanced statistics, regression and custom tables - of which you'll be needing.

Input your student ID or attach your student contract for their vetting and IBM will process and allow you to purchase the pack.
