Also, make sure your handwriting is neat and readable.   Homework Problem On Homework Assignment 1, the general consensus was that I was not in a relationship.Although I definitly did not ask for your opinions... many of you commentedthat I have some psychological work to do before entering into a committedrelationship. Since then, I have collected psychological data from a group of people, measuringtheir “Big Five” traits: Openness, Conscientiousness, Extroversion, Agreeableness,and Neuroticism. I also had these people provide a “Relationship SatisfactionScore” on a continuous scale from 0 to 100. (You can assume that the experimentwas conducted well, the sampling…
