MEASUREMENT & STATA INTRO Dependent Variable: things need to be explained Consequences, Results Independent Variable” things do the explaining part Reasons, Causes Falsifiable: Can we come up with a method/evidence to prove it’s wrong? Testable: Can it be tested in reality? If not. Is it because we cannot come up with such a method or evidence (unfalsifiable)? Or because this method is impractical to implement (impractical to test)? MEASUREMENT Theories, which posit causal relationships between concepts . The goal of science more generally is to test these theories using data Theories: relationships between CONCEPTS Data: relationships between VARIABLES Theories can generate data, we can also say data supports the theory Measurement is the act of turning a concept into a variable. Ie: It’s how we go from the concept of “being liberal” to numbers in a spreadsheet. Basic Process: Concept-> Conceptual definition -> Operational definition ->variable

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
