This may seem like an easy question but I'm interested in knowing if anyone has opposing evidence. All I have is this link http://www.labtestsonline.org/understanding/analytes/testosterone/faq.html#3 which says there is. I often read science articles which state something along the lines of 'people with high testosterone have X quality and people with low testosterone have Y quality' and wanted to know how to tell how much I have. And if that's true, does that mean that ethnicities that are hairier also have differences in the various attributes that testosterone affects or are there other biological mechanisms that can affect hair growth besides testosterone?

There supposedly is a correlation provided ALL OTHER things are equal. I mean comparing a hairless native American and a hairy northern European and thinking their test levels is based on their bodyhair difference is wooish.

No hard scientific data in the post I'm about to make, but based on logic, observation, and anecdote I would say it is an unreliable indicator, at best. There are too many factors determining one's hairiness.
Many traits that tend to correlate with high testosterone can be found in individuals with only small amounts of body hair. I have known deep-voiced, muscular, large framed men with very hairless bodies. As well as many seemingly effeminate, skinny, high voiced men with lots of body hair.
That being said, I would think there would be sometimes a correlation between the amount of testosterone and the extent of the manifestation of genetic potentialities. So if one had genes making heavy body hair possible, more testosterone would likely result in more body hair.
But as a previous poster pointed out, there are certain groups and individuals who are not likely to have much body hair regardless of the amount of testosterone their bodies are producing.

More body hair is a really scary thought. I would become a 5'7" bigfoot...

There are two different testosterones, A and B. One is related to hairyness, the other to other sex traits. Google is your friend.

Link? Are you sure you aren't thinking of synthetic testosterones?

Isn't hairiness an evolutionary trait due to climate? In every other mammal isn't its main function to control body temp followed by as a mating display? So perhaps a robust hair display is seen as a testosterone level indicator to a possible mate - at least in non humans. Bald humans seem to do just fine mating and hence the trait continues. Or maybe their body hair display just makes up for the head one

On the other hand, in humans head hairiness is also a female trait used to attract a mate, so the less of it the more masculine you are! Okay, not really, lousy logic I know
