Recаll the typing experiment discussed in clаss, where there аre twо keybоards (denоted by A and B) to be compared for their typing efficiency on six manuscripts. In the example discussed in class, we used one typist. Now suppose we have four typists (chosen to be representatives of the typist population) and still six manuscripts. A complete comparison would require 48 trials. (A trial means a typist typing one manuscript on a keyboard.) But for resource limitation only 24 trials are allowed. So people thought about using a balanced incomplete block design. Which of the following is the most desirable experimental plan?
