Welcome!• Introduction• Session I
– How to teach with contingency tables– DataCounts! tutorial– Interactive DataCounts!
demonstration
• Session II– Individual activity and work time
• Wrap-Up

Contingency Tables• Contingency Tables
– Allow students to understand the relationship between two variables and introduce additional variables simultaneously.
• Highlight social trends and concepts– What affects income?– What household types are the more likely to
be in poverty?– How do levels of education between
immigrants and native born citizens compare?• Contingency tables using real world data
bring abstract social concepts to life.

Welcome to DataCounts!

WebCHIP Demonstration
• Starting with a question– Do immigrants who entered the U.S.
recently earn less than those who entered decades ago? (How does the year of entry affect earnings for immigrants?)
– Does race make a difference?
5
WebCHIP Demonstration
• Using 2005 American Community Survey data, we will look at the data set: workim05.dat
• This data set looks at full-time, year-round, civilian workers, age 25+ for race, gender, age, immigration, education and earnings variables.
6
• We will use an extract of the 2005 American Community Survey
• What would we expect to see in a table that answers the question?
