Are there statistical techniques specific to computer science research?
Although statistical techniques are fundamentally the same, specific approaches to the use of statistics in experimental analysis of algorithms or more broadly in the analysis of computer systems performance (including aspects of hardware, networks, etc.) are an important topic.  A couple of references to look at include:

C. C. McGeoch.  A Guide To Experimental Algorithmics.  Cambridge University Press, 2012.
