Bivariate Relationships Featuring Two Continuous Variables

Abstract

In this chapter, we discuss bivariate relationships between two continuous variables. In research, these are the relationships that occur the most often. We can express bivariate relationships between continuous variables in three ways: (1) through a graphical representation in the form of a scatterplot, (2) through a correlation analysis, and (3) through a bivariate regression analysis. We describe and explain each method and show how to implement it in SPSS and Stata.
