LESSON: Correlation

Last week, you learned how to create scatter plots to represent bivariate data. When we graph bivariate data on a scatter plot it becomes easier to determine the relationship that exists between the two variables. You learned how to recognize positive and negative correlations as well as linear and nonlinear correlations by looking at scatter plots. Take a minute to review these types of graphs.

Remember when constructing scatter plots, the independent variable (x) is measured by the horizontal axis and the dependent variable (y) is measured by the vertical axis.
