Bivariate Analysis
Examine Relationships between Two Continuous Variables
Use the Bivariate platform to investigate the relationship between two continuous variables. The scatterplot provides a graphical view of the data. Options enable you to fit simple linear regression lines, polynomial regression curves, or smoothers to the data.
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).
