The question is in the header, but I would extend the context a bit.
Next semester I am due to be a teaching assistant (TA) in a course in statistics, where I would need to help sociology students learn to use SPSS. I don't know SPSS, yet, and would like to learn how to use it.
I was thinking of taking a simple dataset, and start reviewing it with methods I know, thus starting to map out where are methods I know of. And once finished, to try and explore more options.
Can someone propose other/better strategies to master a new statistical graphical user interface (GUI)? (in my case SPSS, but it could apply to many other GUI's).
