pet peeve # 3 - ambiguous definitions
Degrees of freedom can be defined as:

  • the number of independent pieces of information that go into the estimate of a parameter
  • the number of values in the final calculation of a statistic that are free to vary
  • the number of independent components minus the number of parameters estimated
  • measure of variability which merely expresses the number of options available within a variable or space
  • (my favorite) a mathematical property of a distribution related to the number of values in a sample that can be freely specified once you know something about the sample
Call me stupid, but I find it pretty freakin' frustrating mildly annoying, when I read five definitions for a concept and still do not understand it enough to explain it to my grandmother.

This reminds me the abstract instructions they used to put on electric appliances with one button - "the operation of this electric appliance is performed by compressing the red-colored knob at the front of the appliance". These instructions are also known as "Push the red button!".

Cruel World

I agree this is a weird and very cruel world we live in :) We can't deny that they is more than one interpretation to the same concept and each one claims to be the right now with no regard to the existance of other conflicting definition. That's what we get when we have a freedom of speech and democratic era :) Imagine how simple it would be if government dictated one definition and everyone would stick to it. While in our case, coordination between authorities in order to simplify our poor student lives is less important then advertising your own name/authority. I have come across same complications in my Computer Science discipline. Feel your pain.

It's definitely a cruel world, but I think here it's my mathematico-abstract stupidity that's to blame...
