Psychological Statistics

I was recently asked to give a talk to our graduate school annual conference. I offered several titles and the one they picked was Using R in research. I'm not sure if this was a good idea or not. The graduate school covers PhD students across three areas of the university: social sciences (including psychology), law and business. In addition the students tend to specialize in either qualitative or quantitive research methods, so I was talking to an audience who might know nothing about statistics or a great deal (e.g., several students have completed MSc courses in psychological research methods here or elsewhere).

My solution was try and explain the advantages of R relative to alternatives such as SPSS (probably the most common statistic package in the University).
