I need to do a statistical analysis of the data. I used a trial version of SPSS for a month, this period has expired and I still need free access to SPSS.
Being a commercial software, SPSS is not free after the trial period ends. But you can switch to a free statistics software such as R which also allows you to conduct all kinds of statistical analyses.
Thank you so much for your helpful answers. All answers advise learning other software than SPSS (R, PSPP, Minitab). I think it is a better way to overcome the difficulty of accessing SPSS.
