Re: Experiments with large N



Not only related! Just to clarify, I do not recall exactly when I pointed this out, but whenever I did, I was certainly referring to just this study. (There is, for example, a link to this work from my sound morphing web page http://www.cerlsoundgroup.org/Kelly/ soundmorphing.html)

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.

So far it looks that the experiment with the largest N (513!) is "The role of contrasting temporal amplitude patterns in the perception of speech" Healy and Warren JASA but I didn't check yet the methodology to see whether is a between or a within subject design.
