QUESTION 10 Sometimes including independent variables in a regression serve as a "data sanity check," in so much as they facilitate a: O more unbiased estimate of the treatment effect O comparison between the estimated coefficient for that variable and the value for that coefficient as predicted by theory O more efficient estimate of the treatment effect in question O secondary measure of the standard error of the treatment effect of interest. QUESTION 11 What are the two primary criteria for identifying "good" controls? O They are likely correlated with treatment and they influence the outcome. They are likely correlated with the treatment and do not influence the outcome. O They are likely uncorrelated with the treatment and they influence the outcome. O They are likely correlated with the treatment and they do not influence the outcome per se.
