two groups where group membership does not directly determine earnings, though does affect level of schooling and hence indirectly affects earnings. Then the IV estimate is the difference in average earnings across the two groups divided by the difference in average schooling across the two groups. 4.8.5 Covariance and Correlation Analysis

Causal inference using regression on the treatment variable

treatment variable 9.1 Causal inference and predictive comparisons So far, we have been interpreting regressions predictively: given the values of several inputs, the fitted model allows us to predict y, considering the n data points as a simple randomsample from a hypothetical infinite “superpopulation”or probability distribution.

Types of Group Comparison Research

Group membership is the independent variable Experiment - group difference(s) are assigned by the researcher (e.g., type of instruction, an approach to counseling). Group differences do not exist before the study begins 6 Causal-Comparative Research The question being asked is whether, and to what degree, groups also differ on another
