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.
举一反三

- 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.
