Hi. I'm currently doing a course in bioacoustics, and we made a psycho-acoustic experiment consisting in making listening dogs' barks of different sizes to people, and they had to say the size of the dog by listening the barks. We collected recordings of barks on internet, and according to the dogs' breed, we placed them among these 5 categories: very small, small, medium, big, very big.
We wrote down the answers subjects gave us, and now we would like to plot the results to see if people can identify the dogs' size with the voice, and therefore establish a correlation. But we are a little bit struggling with how to do that ... If anybody has any idea, we would be grateful !
