1 March 2010 Teaching with Contingency Tables 1

2 Welcome! Introduction Session I – How to teach with contingency tables – DataCounts! tutorial – Interactive DataCounts! demonstration Session II – Individual activity and work time Wrap-Up 2

3 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. 3

4 Welcome to DataCounts! 4

5 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

6 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

7 We will use an extract of the 2005 American Community Survey What would we expect to see in a table that answers the question? Planning Total 7 When immigrated Earnings

27 Interactive Demonstration Starting with a question – Are immigrants who entered the U.S. recently less educated than those who entered decades ago? (How does the year of entry affect educational attainment for immigrants?) – Does race make a difference? 27

28 Interactive Demonstration Using 2005 American Community Survey Data, we will use 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. We will use the new WebCHIP
