Example?

The "Big Five" personality test might serve as a good example. People are rated on Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism, and these values tend to remain constant throughout the life of the individual. The two most covariant with healthy relationships are Agreeableness and Neuroticism, the lower these are the better. I score at the end maximum of openness because I am inquisitive, but with all of the other values I am near the middle, neither agreeable nor non-agreeable, neither neurotic nor non-neurotic.
