Final answer:
The determining factor in whether the University of Minnesota freshmen liked their dates at the Welcome Week dance was the similarity of values.
Step-by-step explanation:
When the University of Minnesota freshmen were matched for a Welcome Week dance, Hatfield and her colleagues (1966) found that the determining factor in whether they liked each other was the similarity of values. People tend to be attracted to others who have similar beliefs, attitudes, and ideologies. This similarity of values makes it easier for individuals to get along and form connections.
