Videos and lessons to help High School students learn how to
define a random variable for a quantity of interest by assigning a
numerical value to each event in a sample space; graph the
corresponding probability distribution using the same graphical
displays as for data distributions.

Introduction to Random Variables
Introduction to random variables and probability distribution
Random Variable Basics
In this video we discuss the basics of random variables for
statistics and finite mathematics. What is a random variable? How do
we use simple random variables to model basic experiments and record
observations about the frequency of certain events? Several
real-world examples are included to make the concepts concrete.
Random Variables - Definition and Cumulative Density Function (CDF)
Intuitive examples. Definition of a random variable. CDF of a random
variable. Distribution of a random variable.
Introduction to Discrete Random Variables and Discrete Probability
An introduction to discrete random variables and discrete
probability distributions. A few examples of discrete and continuous
random variables are discussed.
Graphing a Normal PDF and CDF
This video shows how to graph the Probability Density Function and
the Cumulative Density Function of normal random variables using
Probability Density Functions
Probability density functions for continuous random variables.
