Re: power,beta, etc.

I think the problem that most students have is that they think we can know whether we've made an error.  I use the courtroom analogy to clarify that we can never know for sure.  You might convict an innocent person or find a guilty person innocent, and we can't know the true state of the world.

As for the name of the fourth cell in the 2x2 table, I'll share what I sent to someone off-list:  Dr. Alan Nicewander, formerly of the University of Oklahoma and now working for some governmental entity, used to say that the cell representing "retain when you should" could be called "the glory."  Then we'd have the power and the glory.  :o)
