A researcher wanted to know if expertise/training in the visual arts would influence preferences for abstract art, more specifically, will those who have trained in the visual art (experts) like abstract art more than those without training in the arts (non-experts). She showed a group of experts abstract art and measured preferences on a 10pt scale (0-9; 0 means really dislike and 9 means really like).

She then showed images to a different group made up of non-experts and measured their preference ratings using the same scale. Do the experts like abstract art more than the non-experts?
