She finds that there is a negative linear association between w and t that is best modeled by the equation t=−2.5w+48.1 . What is the meaning of 48.1 in this equation? A: The people in the study walked an average of 48.1 minutes each day. WebValues between −1 and zero represent less perfect associations. In contrast, a positive relationship is one in which both parameters change in the same direction: as one increases so the other increases. Such a relationship would be described by a correlation coefficient between zero and 1, with 1 representing a perfect linear relationship.
