Discrete Random Variables and Probability DistributionsIn this chapter and the next three chapters, we will begin to study specific data sets of interest in statistics. With all of these data sets, we are interested in how the data items are distributed and what is the likelihood of getting a specific data item from a data set.

Simple Linear Regression and the Correlation CoefficientIn the previous chapters, we have been primarily interested in analyzing single variables. In this chapter, we are interested in analyzing two variables and the relationship between them. The two techniques that we will look at are regression analysis and correlation analysis.
