A survey of 303 students was carried out to examine the student's preferences of 6 universities (London, Paris, Milano, St.Gallen, Barcelona and Stockholm). The first 15 variables of the 17 indicate the preferences of the subjects. For a given comparison the reponses are coded by 1 if the first university was preferred, 2 if the second university was preferred and 0 if no decision was made. The variable ENG characterises the knowledge of English and the variable SEX characterises the gender.
