finals week 10_TYPES OF SAMPLING DESIGN IN RESEARCH METHODOLOGY

Question 1

____________________ is based on the concept of random
selection, whereas ______________ is ‘non-random’ sampling. On element selection basis, the sample may be either unrestricted or restricted.

Answer 1

Probability sampling

non-probability sampling

Question 2

When each sample element is drawn individually from the
population at large, then the sample so drawn is known as
‘___________ _________’, whereas all other forms of sampling
are covered under the term ‘restricted sampling’.

Answer 2

unrestricted sample

Question 3

__________________________ is that
sampling procedure which does not afford any basis for
estimating the probability that each item in the population
has of being included in the sample.

Answer 3

Non-probability sampling

Question 4

Non-probability
sampling is also known by different names such as
____________ sampling, _______________ sampling and ____________ sampling.

Answer 4

deliberate
purposive
judgement

Question 5

In this type of sampling, items for the sample are
selected deliberately by the researcher; his choice
concerning the items remains supreme.

In other words, under __________________________ the organizers of the inquiry
purposively choose the particular units of the universe for constituting a sample on the basis that the small mass that
they so select out of a huge one will be typical or representative of the whole.

Answer 5

non-probability sampling

Question 6

Probability sampling: Probability sampling is also
known as ‘__________ sampling’ or ‘____________ sampling’

Answer 6

random
chance

Question 7

Under this sampling design, every item of the universe has an equal chance of inclusion in the sample.

It is, so to say, a lottery method in which individual units are
picked up from the whole group not deliberately but by some mechanical process.

Here it is blind chance alone
that determines whether one item or the other is
selected.

The results obtained from probability or random

Answer 7

Probability sampling

Question 8

_______________________ ensures the law of Statistical Regularity
which states that if on an average the sample chosen is a
random one, the sample will have the same composition and
characteristics as the universe.

Answer 8

Random sampling

Question 9

This is the reason why
_________________ is considered as the best technique of
selecting a representative sample. In such a design, personal

element has a great chance of entering into the selection of
the sample.

The investigator may select a sample which shall yield results favorable to his point of view and if that happens, the entire inquiry may get vitiated.

Answer 9

random sampling
