Advantages and Disadvantages of a CRD

Advantages of a CRD

• Its layout is very easy.
• There is complete flexibility in this design i.e. any number of treatments and replications for each treatment can be tried.
• Whole experimental material can be utilized in this design.
• This design yields maximum degrees of freedom for experimental error.
• The analysis of data is simplest as compared to any other design.
• Even if some values are missing the analysis can be done.

Disadvantages of a CRD

• It is difficult to find homogeneous experimental units in all respects and hence CRD is seldom suitable for field experiments as compared to other experimental designs.
• It is less accurate than other designs.
