WebScatter Plot. The basis of both correlation and regression lies in bivariate ("two variable") scatter plots. This type of graph shows (x i, y i) values for each observation on a grid. The scatter plot of the illustrative data set is shown below: Notice that this graph reveals that high X values are associated with low values of Y. That is, as ... WebThe correlation coefficient is a number that is used to measure the direction and strength of the linear association between two variables. The direction is either positive, negative, or neither. The strength can be described as weak, moderate, or strong.
