The focus of this PullOut is on analyzing
survey data using twoway
tables. In the first activity, students
learn to summarize data from two
survey questions in a twoway 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 PullOut address
standard SID5 from the Common
Core State Standards for High School
Mathematics:
Summarize categorical data for
two categories in twoway 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.
