other factors which require small experimental units.
A. CRD.
B. GLSD.
C. SPD.
D. RCBD.
54. We concerned with

55. 2K in
factorial design means K factors each at any

56. If in a block the number
of units is less than the number of treatment s, then the block is said to be
A. Complete.
B. Incomplete.
C. Unit <
treatment, block.
D. Insufficient
block.
57. Zero years is recorded as
A. Age under Half year.

confounding is used to reduce the
A. Standard error.
B. MSE.
C. Block size.
D. Degree of freedom.
59. Confounding ensures
more precise estimate of lower order interactions at the cost of higher
interactions which are confounded with the
A. Treatments.
B. Blocks.
C. Factors.
D. Levels.
60. Confounding may not
be suitable when the same precision for all treatments comparison is
A. Not required.
B. Required.
C. Seldom required.
D. Suitable
61. If
(i) each treatment is
replicated the same number of times.
(ii) each pairs of
treatments occur together in the block the same number of times.
(iii) b > r > λ
Where
b = blocks
r = replications
λ = each pairs of
treatments occur together in the blocks
Then design is said to be
A.
Incomplete
block design.
B.
Complete
block design.
C.
Balance
incomplete block design.
D.
Block
design.
62. A BIBD is said to be
symmetrical if
Number of blocks =
A. Number of factors.
B. Number of
treatments.
C. Number of levels
D. Number of degree of
freedom
63. In BIBD every pair of
treatment should occur λ times together in the design, thus constraint on BIBD
sometimes requires very large number of blocks or very large block size. To
overcome this difficulty we consider
A. PBIBD.
B. SSPD.
C. SSPD and ANOVA.
D. ANOCOVA.
64. Some pairs of
treatments appear together λ1 times
, some pairs of treatments appear together λ2 times……………and the remaining pairs λm times.
A. In
BIBD.
B. In PBIBD.
C. In GLSD.
D. In RCBD
65. Wishart distribution
is the multivariate generalization of
A. t- distribution.
B. Binomial distribution.
C. Chi-square
distribution.
D. Normal
distribution.
66. (Number of male
/number of female) Χ (1000).
A. Gender ratio.
B. Spouse ratio.
C. Sex distribution ratio.
D. Sex ratio
67. Multinomial distribution is the multivariate generalization
of
A. Normal
distribution.
B. t- distribution.
C. Binomial distribution.
D. Chi-square
distribution.
68. Hotelling T2 distribution is the multivariate
generalization of
A. Normal
distribution.
B. t- distribution.
C. Binomial distribution.
D. Chi-square
distribution.
69. we mean a plan used
to collect the data relevant to the problem under study in such a way as to
provide a basis for valid and objective inference about the stated problem.
A. By testing of hypothesis.
B. By an experimental design.
C. By regression analysis.
D. By correlation analysis.
70. usually consists of the selection of
treatments whose effects are to be studied, the specification of the
experimental layouts, the assignment of treatments to the experimental units
and the collection of observation for analysis.
A. A program.
B. A survey.
C. A plan.
D. A target.
71. There two types of
designs.
Systematic design
and

does not give a picture of the permanent population of a country.
A. Dejure.
B. Defecto.
C. General
D. Specific
74. The unit of
information in sample survey is not the individual person in population.
A. True.
