POL222H1 Chapter Notes - Chapter 2: Dependent And Independent Variables
Document Summary
A good theory is one that, after going through the rigors of the evaluation process, makes a contribution to scientific knowledge. Changes the way we think about some aspect of the world. Must be caused, not driven by data alone, empirical, non- normative, general, and parsimonious. 2. 2: promising theories offer answers to research questions. Think about how a theory would contribute to knowledge. Time series measure: spatial dimension is the same for all cases and dependent variable is measured at multiple points in time. Cross-sectional measure: time dimensions is same and dependent is measured for multiple spatial units. Make theories more general, not specific / one case. Ex: international conflict increases support of the president. Take skeptical look at research of others and develop your own theories. What causes of the dependent variable did the previous researchers miss. How might this theory work at different levels (micro/macro) 2. 6: think formally about the causes that lead to variations.
