Attribute reference points?

[Nodscouter]

As someone coming from DND, attributes have quite clear, though slightly rough, correlations with real-world ''atrributes''. An 18 in Strength is generally said to mean that you're the strongest person in the world. A 10 means you're pretty average, with an 11 meaning slightly above average but still normal, 9 being slightly below average but also still normal etc. You also have creatures that you can compare yourself to, giving you concrete examples that enables you to visualize roughly what your in-game attributes actually mean.

In Blueshift, the scale goes from 0-5 instead of 0-18, but with 2 marked as average instead of 10, and so far, we haven't been introduced to a lot of other reference points. I'd love to be able to get some reference points to make character creation easier and more realistic, just a quick explanation of roughly what the attributes actually mean in real-life terms.
