Detailed explanation-1: -The correlation coefficient has a range of possible values between-1 and +1, with-1 denoting a fully linear negative correlation (sloping downward) and +1 denoting a perfectly linear positive correlation (sloping upward).
Detailed explanation-2: -The coefficient of determination is a number between 0 and 1 that measures how well a statistical model predicts an outcome. The model does not predict the outcome. The model partially predicts the outcome. The model perfectly predicts the outcome.
Detailed explanation-3: -Regression coefficients are independent of change of origin but not of scale. If one regression coefficient is greater than unit, then the other must be less than unit but not vice versa. ie. both the regression coefficients can be less than unity but both cannot be greater than unity, ie.
