Study Notes

Non-Probability Sampling

Non-probability sampling is a sampling technique where the selection of units is based on non-random criteria, such as convenience, judgment, or expertise.
One of the challenges of non-probability sampling is that the results may not be representative of the population being studied.

Risks and Limitations

A risk associated with non-probability sampling is that the sample may not be representative of the population, leading to biased results.
Data collected using non-probability sampling should be used with extra caution because the sample is not randomly selected, which may affect the generalizability of the results.
Non-probability sampling assumes that the sample is representative of the population, but this assumption may not always hold true.
