Question
 Which of the following is true for a completely
randomized design?Solution
In a completely randomized design (CRD), the number of replications for each treatment does not have to be the same. The key characteristic of a CRD is that each experimental unit (subject or plot) is randomly assigned to one of the treatment groups. The random assignment helps to control for extraneous variables that could affect the experimental outcome.
