Hypertension Automated blood-pressure measuring devices have ap- peared in many banks, drugstores, and other public places. A study was conducted to assess the comparability of machine readings vs. readings using the standard cuff [13]. Readings were taken using both the machine and the stan- dard cuff at four separate locations. The results are given in Table 12.31. Suppose we want to test whether the mean difference between machine and standard cuff readings is consistent over the four locations (ie, if the bias is compa- rable over all four locations). 12.9 Is a fixed-effects or a random-effects ANOVA appro- priate here? 12.10 Test whether the mean difference is consistent over all four locations. 12.11 Estimate the proportion of the variance attributable to between-machine vs. within-machine variability.
