Defining Random Variables is a part of the VCE Maths Methods topic Probability and Statistics and subtopic Statistical Inference.
This post looks at:
- random variables, including the concept of a random variable as a real function defined on a sample space
- examples of discrete and continuous random variables
The Language of Probability
The following video defines terms commonly used in probability.
What is a Sample Space?
A sample space is the set of all possible outcomes. For example, if the experiment is tossing a coin, then the sample space is a head and a tail. The video below explains how to answer questions that ask you to identify the sample space.
The following video explains how to find the sample space of two events occurring simultaneously.
What are Discrete and Continuous Variables?
The following video explains the idea of discrete and continuous variables.
