Hmm, that sentence at the beginning is already wrong. Random variables can measure anything, not just numbers. Heads or Tails of a coin, or colours of cars etc.
It's fine to restrict yourself to numeric random variables only. But if you are writing a rant telling other people to be more careful in their analysis, you better dot your i's and cross your t's yourself.
