- In a single replicate of the[img=17x23]1803a1f52b792fd.png[/img] factorial design, since there is only one experimental data at each test point, the variance of the results under this experimental condition cannot be obtained, so we cannot determine the dispersion effect of the single replicate of the factorial design.
- To replicate an experiment means to ( ). A: use control groups and experimental groups B: use statistics to determine the effect of chance C: control for the effects of extraneous variables D: repeat the experiment using either identical or improved research methods
- A Pareto diagram is used to ______. A: identify nonconformity types B: provide a quick look at the data at a single point in time C: determine the effect of a corrective action D: determine the equation of a scatter plot
- The results of this research may be used to cope with stress. _______, the present research contained some limitations. One limitation is that data was only collected on one single occasion.
- In no country other than Britain, it has been said, （） experience four seasons in the course of a single day. A: one cannot B: one can C: cannot one D: can one
