Document Summary
Demonstrates understanding of why these data are observational; applies to mobility context. Good questions and discussion: applies concepts fairly well. Great questions and excellent discussion: compares regression 1 and 2. Recognizes the non-linearity in graph 1 and that the log-log transformation corrects it. Reinforces this observation by correctly explaining graphs 1a and 2a. Not addressed or serious conceptual errors difficulty applying. Correctly interprets the slope in regression 2 (log-log specification). A ten percent (not percentage point) increase in the fraction of. Hhs led by a single mom (e. g. from 0. 20 to. 0. 22) is associated with 4 percent decrease in. Am on average. (1% instead of 10% is fine too) Some familiarity concepts fairly understanding with concepts well but no numeric example and full application: interpretation of the intercept. Recognizes that the intercepts have no interpretations (in any regression) because an x value of 0 is outside the range of the data. Full/direct interpretation: fully interprets slope in linear specifications.
