Chapter 3 Discrete Random Variables and Probability Distributions
Section 3.1: Random Variables
For a given sample space S of some experiment, a random variable (rv) is any rule that
associates a number with each outcome in S. In mathematical language, a
Chapter 4 Continuous Random Variables and Probability Distributions
Section 4.1: Probability Density Functions
Recall from Chapter 3 that a random variable X is continuous if its set of possible values consists
of all numbers making up a whole interval or
Chapter 5 Joint Probability Distributions and Random Samples
Section 5.1: Jointly Distributed Random Variables
There are many situations in which more than one rv will be of interest to an investigator, and so
we will look at how to deal with these cases.
Chapter 6 Point Estimation
Section 6.1: Some General Concepts of Point Estimation
Statistical inference is almost always directed toward drawing some type of conclusion about one
or more parameters (population characteristics). To do so requires that an i
