Just came across a couple of interesting sites for SPSS users: both may involve payment, but can be browsed first.
1: Laerd Statistics
https://statistics.laerd.com/features-overview.php is aimed at students and teachers. Based on SPSS, but before signing up, you can browse through the statistics notes which are applicable to any similar data. https://statistics.laerd.com/pricing.php carries interactive currency pricing (£, $ €: very reasonable) for one to six months access.
2: Profile
http://dangerousenterprises.com/profile.html is aimed at marketing users and is a customer profiling add-on for IBM SPSS Statistics which can be added to the GUI. Free trial offered, but you can access the user guide on: http://dangerousenterprises.com/content/downloads/Users%20Guide.pdf
