Statistics: Two-way Tables and Association
by Texas Instruments

#### Objectives

• Students will be able to summarize data from a two-way frequency table.
• Students will be able to interpret conditional probabilities from a two-way table.
• Students will be able to interpret expected values from a simulation as an estimate of outcomes.
• Students will be able to interpret expected values as an indication of association.

#### Vocabulary

• association
• conditional probability table
• random sample
• survey
• two-way frequency table

#### About the Lesson

This lesson involves analyzing the results of a survey using a two-way frequency table.
As a result, students will:

• Interpret what the values mean in both the frequency table and conditional probability table.
• Use a graph of the relationship between two items from the survey to report conditional probabilities.
• Generate a simulated sampling distribution and interpret how likely a given outcome is expected to occur.
