"Compared to the Germans whom Fritz studied, Mafa listeners varied more widely in matching emotions with the tunes - but overall, both the German and the Mafa groups performed above chance level." - Joe Palca & Flora Lichtman Annoying
What's the meaning of "above chance level" here?
@Justin Xu,
chance level is the level that would be expected by random choices.
chance level of calling the correct heads/tails in coin flips is 50 out of 100 with some slight statistical variation. Someone calling the coin correctly 80 times out of 100 would be above chance level.
