Multiple randomization events occur in an RCBD, but only one randomization occurs in a CRD. It is correct to report that the blocking factor is non-significant, but it is incorrect to change your analysis to a CRD if you have randomized according to an RCBD.

This design … WebCompletely randomized design – description – layout – analysis – advantages and disadvantages Completely Randomized Design (CRD) CRD is the basic single factor design. In this design the treatments are assigned completely at random so that each experimental unit has the same chance of receiving any one treatment. But CRD is …
WebThis is an example of a completely randomized design where there are no other factors that we are interested in other than the treatment factor percentage of cotton.
