BIDIMENSIONAL MEASURES
Completion requirements
In this chapter, we will explore commonly used bidimensional measures in descriptive statistics. We will begin by introducing bidimensional descriptive statistics in Section 3.1. Then, we will present the measure of covariance and its properties in Section 3.2. Section 3.3, we will focus on various types of correlation measures, including the Pearson correlation coefficient, Spearman correlation coefficient (rho), Kendall’s tau correlation coefficient, and point biserial correlation. In Section 3.4, we will delve into the chi-square test of independence. To wrap up, we will provide exercises and their solutions in
Sections 3.5 and 3.6
