Descriptively, yоu're curiоus аbоut the difference in college аttendаnce rates between students who take at least one "advanced placement" (AP) class in high school (X=1) vs. students who never take any AP class (X=0). You have data on "number of AP classes taken" for every single student who graduated from high school in Missouri in Spring 2020. You also have data from every single college/university in Missouri on every student enrolled for Fall 2020. For each student in your first dataset, you assign X=0 or X=1 depending on the number of AP classes, and then you generate Y=1 if they appear in your Fall 2020 enrollment dataset or else Y=0. Consider two points:A. your first dataset excludes students who should have graduated from high school in Spring 2020 but dropped out (i.e., will not even graduate high school); they all should have Y=0 and (almost all) X=0, but instead they do not appear in your sample.B. the very best Missouri high school students (who all have X=1) often attend college in other states (like Stanford in CA, Harvard in MA, etc.), so they are incorrectly coded as Y=0. For your estimator of the mean difference E(Y|X=1) - E(Y|X=0), point A causes _____ bias, and point B causes ____ bias.
