The results of the experiments in this section contradict these common beliefs, and suggest that we may need only a relatively small number of samples (or representatives) after all. However, as Experiment 7-10 and Table 7-3(b) suggest, we may still need a large number of samples to ...

Often the samples are obtained from a factorially designed experiment. In this way more information can be obtained to help understand the reasons underlying the final response. In other applications, a representative range of samples is chosen, such as in the case of predicting the authenticity ...
When analyzing the error in an experiment, "the sample was contaminated during the preparation process" is most likely to lead to _. A. a large random error B. a significant systematic error C. a negligible error D. an E. rror that can be easily corrected 相关知识点: ...
Because many sample size calculations result in the requirement of an unrealistic number of patients, the statistician is often asked to find ways to decrease the number of patients needed. Besides increasing the tolerated type I and/or type II error of the experiment, the most common approaches...
