What's it(s) mean?

[j4]

I asked AQA: "What's the average length of time for which UK jobs at AQA are advertised on the website? i.e. How long does it take for all/any positions to be filled? Thanks!"

AQA replied: "There's no average length of time, it just depends on the number of vacancies and the response. AQA advises applying immediately when they're advertised."

Now, call me a pedant, but I don't believe it's technically true that there's "no average length of time". I can entirely believe that they don't set a maximum or minimum length of time, and/or that they just don't want to tell me, but that's an entirely different kettle of question marks.

Oh, I'm sorry. I didn't actually think through what calculation was right, merely that you stand a fair chance of getting a finite answer. I think, I meant average amongst those, or "apply to those a process producing an average", rather than "MWAHAHAHAHAH I AM AN AVERAGING MONKEY GIVE ME ANY NUMBERS AND I'LL ADD THEM UP AND DIVIDE BY N HAHAHA".

I think *why* I forgot was probably being a mathematician, not a statistician and instinctively solving the case where there's an effectively infinite number, so the special case at the end is insignificant.
