Categorical Logic. Chapter 7. This chapter focuses on the G (good grounds) condition of ARG and deals with simple deductive arguments.. Deductive Relationships. One statement deductively entails another if and only if it is impossible for the second one to be false, given that the first one is true. (page 178). Slide . 1. <. p>Sample . bold display. P.

Some variables are inherently categorical, for example:. Sex. Race. Occupation. Other categorical variables are created by grouping values of a quantitative variable into classes. . Introduction; Displaying Distributions with Graphs. Statistics is... The science of data.. We begin our study of statistics by mastering the art of . examining data. Any set of data contains information about some group of individuals, organized by variables. . Slide . 1.
