Review of sampling articles

1. Presentation

2.  Title=Sampling: Why and How of it?
 Authors=Anita S Acharya, Anupam Prakash, Pikee
Saxena, Aruna Nigam
 sample’ is a subset of the population, selected so
as to be representative of the larger population

3. 1. Non-probability sampling
includes
Convenience/purposive
sampling, Quota sampling,
Snow ball sampling
2.Each method of sampling has
its own advantages and
limitations
3. probability sampling is
preferable, since its results
can be generalized.

4. •Title= Comparison of Snowball Sampling and Sequential
Sampling Technique
•Authors= Ilker Etikan, Rukayya Alkassim and Sulaiman
Abubakar
• Description and comparison of two non-random samplings

5. •Linear snowball sampling= snowball sampling in which the
researcher recruits a single participant, while the second
nominee recruits the third participant. The chain continues
to refer linearly up to the end of the sampling.
•Exponential Non-Discriminative Snowball Sampling= where
every recruited participant in the research work recruits
another participant
•Sequential Sampling= advance but is determined according
to mathematical decisions on the basis of information
yielded as survey progresses. This design is usually accepted

6. Article 3
•Title=Comparison of Convenience Sampling and
Purposive Sampling
•Authors=Ilker Etikan, Sulaiman Abubakar Musa,
Rukayya Sunusi Alkassim
• Two non-probability sampling techniques namely,
Convenience Sampling and Purposive Sampling.

7. •Non-probability sampling has a lot of limitations due to the subjective
nature in choosing the sample and thus it is not good representative of
the population
• it is useful especially when randomization is impossible like when the
population is very large
•Convenience Sampling and Purposive Sampling depends on the nature
and type of the research.
