These exercises were written to accompany a course in critical thinking. The exercises are divided into five sections: the scientific approach, argumentation, causal arguments, testing causal claims, and common errors in critical thinking.
These exercises use the 2018 General Social Survey (GSS) and a statistical program, Survey Documentation and Analysis (SDA), which was written at UC Berkeley. Both the GSS and SDA are freely available wherever you have an internet connection. There is a brief introduction to SDA at the end of the exercises.
