Which of the following is NOT true of one-way analysis of variance experimental design? Choose the correct answer below. A. Using a rigorously controlled design is one way to reduce the effect of extraneous factors. B. Good results require that experiments be carefully designed and executed. C. In any design, if the conclusion is that the differences among the means are significant, the differences are explained by the factor used. D. A completely randomized experimental design is one way to reduce the effect of extraneous factors.

C

Explanation:

One way analysis of variance (one-way ANOVA) design experiment is used in an experiment where there is only one factor. One-way ANOVA experimental design helps to reduce the effect of extraneous factors using a rigorously controlled design and completely randomized experimental design However, good results require that experiments be carefully designed and executed.

This is not true one-way ANOVA experimental design that In any design, if the conclusion is that the differences among the means are significant, the differences are explained by the factor used
