# General Questions

What are the advantages of a Completly Randomized Design (CRD)?

What are the disadvantages of a CRD?

What are the advantages of using a Randomized Complete Block Design (RCBD)?

What are the disadvantages of using a RCBD?

If multiple replicates of each treatment can be accommodated in each block of a blocked design which disadvantages of a RCBD are removed?

What are the advantages of a Latin Square Design (LSD)?

What are the disadvantages of a LSD?

An experiment is to be designed to explore the impact of two factors (call them A and B) on a response. Suppose one factor (A) is to be examined at 5 levels and the other factor (B) is to be examined at 5 levels, how many treatments must the experiment accommodate?

For question 8, how many experimental units must we have if we wish 4 replicates of the complete set of treatments?

For question 8, how many experimental units must each block contain if you wish to use a RCBD for our experiment?

For question 8, how many experimental units must we have if we wish to implement a Latin Square Design using factor A for the row factor and another factor, factor C for the column factor?

For question 8, how many experimental units must we have if we wish to implement a Latin Square Design for our treatments but now the row factor is a fourth factor, factor D, and the column factor is still factor C, and the treatment is the factorial in factors A and B?
