Use the Bivariate platform to investigate the relationship between two continuous variables. Interactively add a simple linear regression line, polynomial regression curves, or smoothers to a scatter plot. Using the scatterplot, you can see at a glance the relationship between the two variables.
The Bivariate platform is the continuous by continuous personality of the Fit Y by X platform. The word bivariate simply means involving two variables instead of one (univariate) or many (multivariate).
