The focus of this Pull-Out is on analyzing
survey data using two-way
tables. In the first activity, students
learn to summarize data from two
survey questions in a two-way table.
They begin their analysis of the data
by computing joint and marginal
percentages. In Activity 2, students
calculate conditional percentages and
use their results to explore relationships
between the responses to two
survey questions. In Activity 3 students
conduct their own surveys and
then analyze the results.
The activities in this Pull-Out address
standard S-ID-5 from the Common
Core State Standards for High School
Summarize categorical data for
two categories in two-way frequency
tables, interpret relative
frequencies in the context of the
data (including joint, marginal,
and conditional relative frequencies).
Recognize possible associations
and trends in the data.
