Many diagnostic tests are indicative of problems only if a child scores in the upper 10 percent of those taking the test (at or above the 90th percentile). Many of these tests are scaled to produce T scores, with a mean of 50 and a standard deviation of 10. What would be the diagnostically meaningful cutoff?
Answer to relevant QuestionsGive one example each of an analytic, a relative frequency, and a subjective view of probability. In Appendix D (or the Add.dat data set on the website), what is the probability that a person drawn at random will have an ADDSC score greater than 50? Using the data from Exercise 7.25, compute the risk and odds ratios of punishment as a function of race. Suppose I told you that last night’s NHL hockey game resulted in a score of 26 to 13. You would probably decide that I had misread the paper, because hockey games almost never have scores that high, and I was discussing ...In the exercises in Chapter 2, we discussed a study of allowances in fourth-grade children. We considered that study again in Chapter 4, where you generated data that might have been found in such a study. (a) Consider how ...
