Question:

Following are the statements pertaining to a strip-plot-design:
A. Vertical strip-plot and horizontal strip-plot are never perpendicular to each other.
B. Precision associated with vertical factor is sacrificed to improve the precision of horizontal factor.
C. The intersection plot is smallest in size.
D. There is no relationship between vertical plot and horizontal plot with respect to their sizes.
E. Precision of intersection effect is lower than main effects of vertical and horizontal factors.
Choose the correct answer from the options given below:

Show Hint

Strip-plot design:
Two factors with different plot sizes.
Intersection plots are the smallest.
  • A and C only
  • B and D only
  • A, B and C only

The Correct Option is D

Solution and Explanation

Step 1: Understanding the Concept:
Strip-plot design is a type of experimental design.
It is used when two factors require large plots.

Step 2: Key Formula or Approach:

No specific formula.
Need to understand the features of strip-plot design.

Step 3: Detailed Explanation:

In strip-plot design:
- Vertical and horizontal strips are perpendicular to each other.
So, A is false.
- Precision of vertical factor is sacrificed to improve precision of horizontal factor.
So, B is false.
- The intersection plot is the smallest in size.
So, C is true.
- There is no relationship between vertical and horizontal plot sizes.
So, D is true.
- Precision of intersection effect is lower than main effects.
So, E is false.
Thus, C and D are correct.

Step 4: Final Answer:

The correct statements are C and D.
Hence, the correct option is (D).
