D)repeated measures design.
E)None of these

Question

Quizplus · Accepted Answer

A completely randomized design involves randomly assigning experimental units to treatments without any blocking or other factors taken into account. This type of design is appropriate when there are no obvious sources of variation other than the treatment itself. Therefore, it is the best choice for comparing treatments based on independently selected experimental units. B) randomized block design and C) two-factor ANOVA involve blocking or grouping the experimental units based on factors that may influence the response variable, such as location or time, and are not appropriate for comparing treatments based solely on independently selected units. D) repeated measures design involves measuring the same experimental units under different treatments or conditions, and is not applicable in this scenario.
