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: -If the correlation coefficient is greater than zero, it is a positive relationship. Conversely, if the value is less than zero, it is a negative relationship. A value of zero indicates that there is no relationship between the two variables.
Detailed explanation-3: -Correlation methods of analysis aim to describe the correlation between two variables. Correlation analysis attests the relation between two or more variables, but does not measure the causal relation between them. Correlation analysis may also indicate the intensity of the relationship between variables.
Detailed explanation-4: -A correlation between variables indicates that as one variable changes in value, the other variable tends to change in a specific direction. Understanding that relationship is useful because we can use the value of one variable to predict the value of the other variable.
Detailed explanation-5: -A positive correlation is a relationship between two variables that tend to move in the same direction. A positive correlation exists when one variable tends to decrease as the other variable decreases, or one variable tends to increase when the other increases.
