Critical Thinking -- Exercises using different data sets to teach critical thinking skills, These data sets include the General Social Survey (various years), the Pew Religious Landscape Survey (2007), the Field Poll (2008), The Pew Religion and Politics Survey (2012), and the 2014 Pew Polarization Survey. Critical thinking in this class refers to the ability to answer why and how questions such as why do people commit crimes and why do people vote the way they do. We focus on using the scientific approach to answer such questions although not all questions are best answered with this approach. Critical thinking also refers to the ability to develop organized and logical arguments and to test hypotheses using the scientific approach. At CSU Fresno critical thinking is a GE requirement. It’s offered in a number of departments and students can take their choice. In Sociology it’s also a requirement for the major. In my class the papers revolve around the analysis of quantitative data. There are five main sections in the class:
- Scientific approach,
- Causal arguments,
- Analysis of quantitative data and
- Fallacies of reasoning.

There are two papers in the course both of which are completed in the section on analysis of quantitative data. The second builds on the first paper and introduces new topics in the analysis of data. Both papers use public opinion data from various sources.
The first paper starts by asking students to explore some topic such as abortion, homosexuality, same-sex marriage or voting. It typically asks students to run a frequency distribution for a variable that describes how respondents feel about abortion, homosexuality, same-sex marriage, or how they voted in a particular election. This variable becomes the dependent variable for their paper. Then the paper turns to a discussion of possible independent variables. Once they have the idea of dependent and independent variables clear then they select particular independent variables to crosstabulate with their dependent variable. The only statistics that students use in the first paper are frequencies and two-variable crosstabs with percentages.
The second paper is a continuation of the first paper. In recent years the second paper has focused on religion and their dependent variable. Religion includes both religiosity (i.e., how religious they are), religious preference (i.e., what religion they are), and other aspects of religion. The second paper includes two-variable tables with religious variables as the independent variables. In addition to percentages, in the second paper the students use Chi Square. Towards the end of the second paper, the idea of elaboration is introduced where students add a third variable into their analysis as a control variable. This allows us to discuss such ideas as spuriousness. I have attached a short discussion of spuriousness that I use in my classes which uses an example from the General Social Survey and focuses on the issue of control of pornography.
Using a statistical package means that the students don’t have to worry about how to compute the statistics. Moreover, they learn a little about the use of statistical packages. I use SPSS for the statistical analysis but you could substitute any statistical package you like to use.
Each year I have a different focus for the papers. Over the last few years we have focused on:
- opinion on various moral issues including abortion, legalization of marijuana, willingness to allow a person to take their own life when they are very sick, homosexuality and same-sex marriage.
- confidence in social institutions such as government, business and science.
- Proposition 8 in California which was the 2008 ballot initiative to amend the California State Constitution to prohibit same-sex marriage,
- voting focusing on the 2004 presidential election,
The papers ask the students to test their causal claims using the following steps:
- state hypothesis,
- develop argument to support argument,
- construct dummy table showing what the data ought to look like if the hypothesis is true,
- get the actual table from SPSS and
- interpret the data including indicating whether the data support the hypothesis.
The papers are named paper 1 and paper 2 and indicate the year of the class and the focus of the paper. The name of each assignment starts with CT for “critical thinking” and then indicates whether it is paper 1 or paper 2. The file name concludes with the topic of the paper and the semester I used the assignment. There are seven sets of papers. The topics for the each set are as follows:
- Spring, 2006 – The first paper focuses on moral issues such as legalization of marijuana, willingness to allow a person to take their own life when they are very sick and sexuality including how respondents felt about adults and teenagers having sexual relations before marriage. The second paper focuses on religion and sexuality focusing on both sexual behavior (number of sexual partners and frequency of sexual relations) and attitudes about sexual behavior (how respondents feel about adults and teenagers having sexual relations before marriage).
- Fall, 2006 – The first paper focuses on abortion. The second paper focuses on religion and sexuality including both sexual behavior (viewing an X rated movie and having had sex with someone other than spouse while married) and attitudes toward sexual behavior (how respondents feel about sexual relations between two adults of the same sex and how respondents feel about a married person having sexual relations with someone other than their marriage partner).
- Fall, 2008 – The first paper focuses on voting in the 2004 presidential election. The second paper focuses on religion and voting in the same election.
- Fall, 2009 – The first paper focuses on how respondents voted on Proposition 8 (same-sex marriage ballot initiative) in the 2008 California election. The second paper focuses on religion and voting on Proposition 8.
- Fall, 2010 – The first paper focuses on how respondents feel about homosexuality. The second paper focuses on religion and attitudes toward homosexuality. The second paper uses a very large survey of religions that allows us to identify particular religions (e.g., Mormons, Baptists, Roman Catholics, and Hindus) and have a large enough sample to compare religions.
- Fall, 2011 – The first paper explores how much confidence people have in various social institutions and how political party preference, socioeconomic status, age and gender are related to confidence. The second paper looks at change over time in confidence and the relationship of religious factors to confidence. It also introduces the idea of spuriousness in data analysis.
- Fall, 2014 – The first paper looks at opinions about same-sex marriage and the relationship of political factors, socioeconomic status and gender with opinions on same-sex marriage. The second paper explores the relationship of religious variables to opinions on same-sex marriage and introduces the idea of spuriousness.
- Fall, 2015 – The first paper looks at opinions about immigrants and immigration and the relationship of political factors, socioeconomic status and gender with opinions on immigration. The second paper explores the relationship of religious variables to opinions on immigration and introduces the idea of spuriousness.
- Fall, 2016 – The first paper looks at opinions about abortion and the relationship of political factors, socioeconomic status and gender with opinions on abortion. The second paper explores the relationship of religious variables to opinions on abortion and introduces the idea of spuriousness.
The data come from various sources including:
- the Field Poll (September, 2008)
- the Pew Forum on Religion and Public Life’s survey called the Religious Landscape Survey (summer, 2007),
- the Pew 2012 Religion and Politics Survey,
- the Pew 2014 Political Polarization Survey, and
- the General Social Survey (in one subset I combined two consecutive years to create a larger sample).
In each instance I created an instructional subset from the larger survey. I selected a smaller set of variables, modified the variable and value labels and the missing values, recoded some variables, created some new variables from the original set of variables and generally made it easier for the students to use the data set. The SPSS data files are named to indicate the source of the data. Note that in the Field Poll data set there are two versions – one has been modified and one has not. The modified version takes the undecideds out of the analysis by including them as a missing value. The one that has not been modified keeps the undecideds in the analysis. The two papers use different versions.
Use of the Data.
