WebSep 11, 2015 · Complete Randomized Design (CRD) is more efficient than Complete Randomized Block Design (CRBD) under controlled environments such as lab … WebA CRD requires that each replicate of a treatment is randomly assigned to an experimental unit (a plot within the larger main field in this case), whereas a RCBD requires that treatments are randomized within each block individually. Multiple randomization events occur in an RCBD, but only one randomization occurs in a CRD. It is dr thorvaldson maitlandWebIf the investigators desire 3 replications for each of the 12 temperature and time combinations (i.e. 12 treatments), a basic CRD or an RCBD (with a suitable blocking factor that would generate the replicates) will require as many as 36 attempts of testing.
