# Design of Experiments Quiz 2

The post contains MCQs on the Design of Experiments Quiz (DOE). Most of the MCQs on the Design of Experiments Quiz are from factorial Experiments. Let us start with Online MCQs on the Design of Experiments Quiz.

Multiple Choice Questions about the Design of Experiments for preparation of examinations related to PPSC, FPSC, NTS, and Statistics job- and education-related examinations

1. The designs in which the number of treatments must be an exact square, the size of a block is the square root of this form separate replications are called

2. An important relationship between the coefficient of determination $R^2$ and the F-ratio used in ANOVA is

3. When a number of confounded arrangements for factorial designs are made in Latin Squares, the designs are called

4. An experiment was designed to investigate the effect of the amount of water and seed variety on the subsequent growth of plants. Each plant was potted in a clay plot, and a measured amount of water was given weekly. The height of the plant at the end of the experiment was measured. Which of the following is not correct?

5. A design with $v$ treatment labels, each occurring $r$ times, and with $bk$ experimental units grouped into $b=v$ blocks of size $k<v$ in such a way that the units within a block are alike and units in different blocks are substantially different is

6. The number of aliases of two-factor interactions in a $2^6$-factorial experiment (1/4 replicate) would be

7. When all pairs of treatments are compared with approximately the same precision, even though the differences among blocks may be large, called

8. The parameter $\lambda$ for a balanced incomplete block design with $a=4, b=4, k=3, r=3$ as usual notation is

9. Which of the following is NOT CORRECT about a randomized complete block experiment?

12. For a two-factor factorial design, if there are ‘$a$’ levels of Factor-A and ‘$b$’ levels of Factor-B, then $df$ of interaction are:

13. In $3^k$ factorial design with $n$ replicates in the experiment, the $df$ of error are

14. In a factorial experiment, if $r$ is the number of replicates then each factorial effect has the same variance, that is

15. In a randomized complete block design, the block should be constructed so that

16. When a factorial experiment is performed in fractional replication, the two factorial effects that are represented by the same comparisons are called

17. Let ADE and BCE be two effects confounded in blocks. Then generalized interaction is

18. If ABC is confounded in replicate I,
AB is confounded in replicated II,
BC is confounded in replicate III,
then the design technique is called

19. The models in which the levels of treatment factors are specifically chosen are known as

20. An experiment was conducted where you analyzed the results of the plant growth experiment after you manipulated the amount of water and seed variety. Which of the following is correct?
