Re: Experiments with large N

[Matt Wright <matt@xxxxxxxxxxxxxxxxxx>]

Trevor Cox recently published the results of an online experiment  
about listeners' ratings of sound files on a six-point scale ("not  
horrible", "bad", "really bad", "awful", "really awful", and  
"horrible").  To date he has 130,000 subjects (!) and about 1.5  
million data points:

Here's the website for his experiment: http://www.sound101.org

Clearly this is related to the "effect of visual stimuli on the  
horribleness of awful sounds" that Kelly Fitz pointed out.
