gothmund,
It might be helpful if you could tell us a little bit about the data you need to analyze, and the type of analysis you need to carry out. If you're boss has some data sets and wants the average, mean, st dev, etc - not using something like excel seems pretty stupid to me. its widely available and easy to use. you could always make up a name for some mythical statistical package, then use excel, and just give him/her the analyzed data
