There are two ways to find a correlation coefficient, r, using the calculator. You can manually enter the calculations yourself, or you can have the calculator do the work for you. First store your bivariate data into two lists, say list L1 for the x-values and list L2 for the y-values. Follow these steps to manually calculate r : a.

Bivariate data comprises of two variables that may or may not have a correlation. A good example of bivariate data was given by the Roman architect, Vitruvius in the first century BC. He claimed that a person’s arm span is approximately the same as a person’s height. We can attempt to prove Vitruvius’ claim by using a bivariate scatter plot.

An ordered pair consists of values of two variables for each individual in the data set. Data that consist of ordered pairs is called bivariate data. Response variable (Dependent variable) is the variable whose value can be explained by the value of the explanatory or predicator variable (independent variable).
