Question: In addition to the data in Table 12.4, Mandel (1972) reported stress test data from five additional laboratories. Summary statistics are given in Table 12.13.
In addition to the data in Table 12.4, Mandel (1972) reported stress test data from five additional laboratories. Summary statistics are given in Table 12.13. Based on just these five additional labs, compute the analysis of variance table and test for differences in means between all pairs of labs. Use α = .01. Is there any reason to worry about the assumptions of the analysis of variance model?
