STAT 414 focuses on the theory of introductory probability. The course goals are:
As the title of Stat 414 suggests, we will be studying the theory of probability, probability, and more probability throughout the course. Here's a (brief!) overview of what we'll do in the course:
In Section 1, one of our primary focuses will be to develop an understanding of the various ways in which we can assign a probability to some chance event. We'll also learn the fundamental properties of probability, investigate how probability behaves, and learn how to calculate the probability of a new chance event.
In Section 2, we'll explore discrete random variables and discrete probability distributions. The basic idea is that when certain conditions are met, we can derive formulas for calculating the probability of an event. Then, instead of returning to the basic probability rules we learned in Section 1 to calculate the probability of an event, we can use the new formulas we derived, provided that the certain conditions are met.
In Section 3, as the title suggests, we will investigate probability distributions of continuous random variables, that is, random variables whose possible outcomes fall on an infinite interval. It's in this section that you'll want to make sure your calculus skills of integration and differentiation are sufficient before tackling many of the problems you'll encounter.
In Section 4, we'll extend many of the definitions and concepts that we learned in Sections 2 and 3 to the case in which we have two random variables. More specifically, we will:
Finally, in Section 5, as the name of this section suggests, we will spend some time learning how to find the probability distribution of functions of random variables. For example, we might know the probability density function of X, but want to know instead the probability density function of X2. We'll learn several different techniques for finding the distribution of functions of random variables, including the distribution function technique, the change-of-variable technique and the moment-generating function technique. The more important functions of random variables that we'll explore will be those involving random variables that are independent and identically distributed.
