A completely randomized design is useful when the experimental units areA)  homogeneous.B)  heterogeneous.C)  ​clustered.D)  stratified.

Paige Boyce · Accepted Answer

Final Answer : A, Explanation :  A completely randomized design is most useful when the experimental units are homogeneous, meaning they are similar or identical to one another. This helps to ensure that any differences observed between treatments are due to the actual treatments being tested, rather than natural differences between the units themselves. If the units were heterogeneous or clustered, a more complex experimental design may be needed to account for these factors. Stratified designs, on the other hand, can be useful when the units can be partitioned into distinct groups based on some relevant characteristic, but this doesn't appear to be the case here.
