I am not sure as I have not really tried it, but as far as I can see, there should be possibilities to overcome at least some obstacles by "audio-lising" rather than "visualising". Using sound(s), i e signals at different frequencies with more or less noise could make it possible to compare samples. Anyone who have tried? In case it works, guess it should be useful in both statistics teaching and stats practice for those who can see too.
