Measures of Bivariate Association
Overview
This chapter discusses procedures to test the significance of the relationship between two variables. Recommendations are made for choosing the correct statistic based on the level of measurement (data type and modeling type) of the variables. This chapter shows how to use the JMP Fit Y by X platform to prepare bivariate scatterplots and perform the chi-square test of independence, and how to use the JMP Multivariate platform to compute Pearson correlations and Spearman correlations.
