A statistics site that I would most commonly use would be the Statistics In Sports site http://www.amstat.org/sections/sis/. This gives you access to different sites that have the statistics of different sports and sport organizations. Working in the athletics field, it is nice to be able to check stats of some of the competing institutions to see where and how they rank.
I have experience using the SPSS software during my undergraduate coursework. I believe I will have to use a lot of different statistical software as an athletic director to help with the budgeting of an institution as well as a way to keep up with the progress of the athletic department.
