From a statistical point of view, two goals of experimental design are to
A) increase both treatment and error variance.
B) increase treatment variance and reduce error variance.
C) increase error variance and reduce treatment variance.
D) reduce both treatment and error variance.

Quizplus · Accepted Answer

The goal of experimental design is to maximize the difference between the treatments, which is represented by treatment variance, while minimizing the variation within each treatment, which is represented by error variance. Therefore, option B is the correct choice as it seeks to increase treatment variance and reduce error variance.
