Question

Differentiate between probability and nonprobability sampling methods?

Answer 1

The difference between non-probability and probability sampling is that non-probability sampling does not involve random selection and probability sampling does. At least with a probabilistic sample, we know the odds or probability that we have represented the population well.

Answer 2

Probability sampling is a sampling technique, in which the subjects of the population get an equal opportunity to be selected as a representative sample. Nonprobability sampling is a method of sampling wherein, it is not known that which individual from the population will be selected as a sample.
