Detailed explanation-1: -The correlation coefficient is measured on a scale that varies from + 1 through 0 to – 1. Complete correlation between two variables is expressed by either + 1 or-1. When one variable increases as the other increases the correlation is positive; when one decreases as the other increases it is negative.
Detailed explanation-2: -A positive correlation exists when two variables operate in unison so that when one variable rises or falls, the other does the same. A negative correlation is when two variables move opposite one another so that when one variable rises, the other falls.
Detailed explanation-3: -They can tell us about the direction of the relationship, the form (shape) of the relationship, and the degree (strength) of the relationship between two variables. The Direction of a Relationship The correlation measure tells us about the direction of the relationship between the two variables.
Detailed explanation-4: -What Is Positive Correlation? A positive correlation is a relationship between two variables that move in tandem-that is, in the same direction. A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases.
Detailed explanation-5: -If the graph of the variables represent a line with positive slope, then there is a positive correlation (x increases as y increases). If the slope of the line is negative, then there is a negative correlation (as x increases y decreases).
