Detailed explanation-1: -A correlation coefficient of zero indicates that no linear relationship exists between two continuous variables, and a correlation coefficient of −1 or +1 indicates a perfect linear relationship. The strength of relationship can be anywhere between −1 and +1.
Detailed explanation-2: -Thecorrelation coefficient (r) is a statistic that tells you the strengthand direction of that relationship. It is expressed as a positive ornegative number between-1 and 1. The value of the number indicates the strengthof the relationship: r = 0 means there is no correlation.
Detailed explanation-3: -Perfect Relationship: When two variables are exactly (linearly) related the correlation coefficient is either +1.00 or-1.00. They are said to be perfectly linearly related, either positively or negatively. No relationship: When two variables have no relationship at all, their correlation is 0.00.
