Consider a study of n = 51 states, including the District of Columbia, on the salaries of public sch teachers. An SLR model for Y = average teacher annual salary ($ thousands) and X = spending per ($ thousands) resulted in the following studentized deleted residuals, leverages, Cook's distances DFFITS for six states.
