Well yes, Mr. Costich, the test results aren't
scientifically valid but it didn't disproved that the
sound differences heard by participants did not
physically exist.

That was another potential flaw in the tests. I see no
controls that ensured that the listeners heard the
identically same selections of music. Therefore, the
listeners may have heard differences that did physically
exist - unfortunately they were due to random choices by
the experimenter, not audible differences that were
inherent in the cables.


Mr. Costich opined that disproving the sound differences
heard by audiophiles do not physically exist is not in
the realm of statistical analysis.


I read all his posts, and saw no such thing. I did see him correct
other such misrepresentions of what he said.



Along this subthread, I said the following to Mr. Costich concerning
the test:


" ... Mr. Costich, the test results aren't scientifically valid
but it didn't disproved that the sound differences heard by
participants did not physically exist."


Mr. Costich replied:

" Of course not. Certainty is not in the realm of statistical analysis...."


He is saying that "certainty" about disproving a claim that the
sound differences heard by participants do not physically
exist -- is not in the realm of statistical analysis.


Further, Mr. Costich supported his claim by saying:


" Because statistical analysis is the only toll we have to test claims
about the behavior of populations from samples. Any such test has
error and the likelihood of error needs to be set in advance. The
significance level is precisely the probabiliy of rejecting a true null
hypothesis."

You seem to suggest that Mr. Costich misspoke, but how so ?

Are you inferring that Mr. Costich was untruthful about what he
said and that he spoke too hastily ?



Basically borglet, you're not a reliable analyst in matters like
these.
