Question

"For a certain experiment, the available experimental units are six people: three females (1) and three males (m). Use (11, 21, 31) to denote the females and (1m,

2m, 3m) to denote the males. There are to be three treatment groups: A, B, and C. If a randomized block design is used, with the experimental units blocked by
gender, which assignment of treatments is not correct?
1 - A: (14,1m), B: (24,2m), C: (3f, 3m)
2 - A: (26,1m), B: (3f, 2m), C: (11, 3m)
3 - A: (11,2m), B: (3f, 21), C: (3m, 1m)
4 - A: (2f, 3m), B: (31,2m), C: (1f, 1m)"

Answer 1

When using a randomized block design and blocking by gender, each treatment should be assigned to each gender. Option 1 is the assignment of treatments that is not correct.

Step-by-step explanation:

When using a randomized block design, the goal is to ensure that each treatment is assigned to each block. In this case, the blocks are defined by gender, so each treatment should be assigned to each gender.

Let's go through each option to see which assignment of treatments is not correct:

Therefore, Option 1 is the assignment of treatments that is not correct.
