Question

Distinguish between Deliberate sampling and Random sampling.

Answer 1

Hint: To distinguish between Deliberate sampling and Random sampling, just follow their basic definitions that are, for deliberate sampling the selection of items is choice based whereas for random sampling the selection of items is chance-based.

Complete step by step answer:
We know that deliberate sampling is a type of non-probability sampling that involves the selection of components based on factors excluding random chance whereas random sampling is a type of probability sampling that provides a calculable and non-zero probability of selection in the sample.
The differences between deliberate sampling and random sampling are as follows:-
(1) In deliberate sampling the items are selected by choice whereas in random sampling the items are selected by chance.
(2) Since the selection of items for deliberate sampling is done by choice, we can say that selection of items may be biased whereas in random sampling the items are selected by chance, so it is not biased.
(3) Deliberate sampling has no further categories. Since the selection of items in random sampling is done by choice, this method can be further divided into the lottery method.
Hence, these are all the differences between deliberate sampling and random sampling.

So, the correct answer is “Option A”.

Note: In this question, one might do a mistake and consider deliberate sampling as a probability sampling technique where the entire probability technique is divided into multiple groups. This is wrong because in cluster sampling the entire probability technique is divided into multiple groups. In deliberate sampling, the selection of items is choice-based.
