Q:"What is the standard deviation in height for humans?"
A: inches and people are not compatible
whereas:
Q: what is the average height of humans?
A: 5.3, with a nice graph showing the +- sigma
So it had the info, but just couldn't understand the question.
Whereas
Q: what is the average height of male humans in Canada?
gives me an answer and chart "weighted for USA demographics".
If I change 'canada' to USA, I get a graph labelled the same, but with a different numerical value.
I don't think I trust this. At least with Google and I can inspect the source, read links, and so on.
One more: "What is a basis vector"
Wolfram gives me the stock quote for BASI, google starts things off with the linear algebra definition followed by a lot of relevant links.

When you use the word "of," the query works fine. http://www.wolframalpha.com/input/?i=what+is+the+standard+deviation+of+height+for+humans http://www.wolframalpha.com/input/?i=what+is+the+standard+de...
