I'm looking for a simple overview of stats, something that won't give
me the formulas, but will give me a sense of what they're about
I'd like to get a very basic understanding of the stats in a paper I'm
(Its an attempt to prove that hypnosis is a real condition, using pet.
...& I think its pretty poor)
left Fusiform x-34 y -72 z -12 zScore 3.69
I get that the first three are spatial coordinates, but what's a
F=8.69 dF=1,7 p=.02
I understand that p= in >= 2% of cases the result is likely to be
but what's F & dF
I guess that's standard deviation?
OK that's a T test.
So what does a T test tell me?
Is there maybe a simple web page that describes this?
The paper is
"Hypnotic visual illusion alters color processing in the brain
