WebIn bivariate data, two variables that can change are compared in order to identify relationships. You will have bivariate data, which consists of an independent and a dependent variable if one variable is impacting the other. This is so that both variables will change if the other one changes. Independent Variable. WebThe correlation coefficient is a measure of how well a line can describe the relationship between X and Y. R is always going to be greater than or equal to negative one and less than or equal to one. If R is positive one, it means that an upwards sloping line can completely describe the relationship.
