Any Statisticians Out There?

I have a question for any statisticians.

I am looking at a presentation given to us at work on a particular subject. (I can't go into details because it's confidential.) Anyway the presentation shows 4 user types for a product, but all four are above average users. I asked the people who conducted the research how all four user types can be above average. Their answer is because there is also a fifth group that won't make use of the product at all, and the average includes this group.

My question is would the average therefore be more meaningful if it was calculated excluding the non-users so that you could see who out of the actual users would be above and below average?

I'm not a statistician, and certainly not a marketeer, so I don't know what is standard practice and what isn't.

Anyone able to help?
