1. Is the NELS math test biased against girls? Conduct an analysis of predictive bias using the base year test (ByTxMStd) and Sex, with 10th-grade Math GPA as the outcome (F1S39a). Make sure you convert Sex into a dummy variable and center the Math test score.

2. The file “ATI Data b.sav” (or the Excel or plain text versions of these data) includes another, perhaps more realistic, simulated data set for the attribute–treatment interaction problem illustrated in the chapter. Perform an ATI analysis and interpret the results.
