Lesson Plan: Expected Values of Discrete Random Variables Mathematics • Third Year of Secondary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate the expected value of a discrete random variable from a table, a graph, and a word problem.
Objectives
Students will be able to
- calculate the expectation value of a discrete random variable from a table,
- calculate the expectation value of a discrete random variable from a graph or a word problem describing a real-world system.
Prerequisites
Students should already be familiar with
- discrete random variables,
- the probability distribution function of a discrete random variable.
Exclusions
Students will not cover
- standard deviation,
- variance,
- continuous probability distributions,
- properties of expectation values (i.e., ).
