In business and medical research, sampling is widely used for gathering information about a population. In stratified sampling, subsets of the population are created so that each subset has a common characteristic, such as gender. Results from probability theory and statistical theory are employed to guide the practice. 4. Connection to stratified sampling Quota sampling is the non-probability version of stratified sampling.

Non-Probability Sampling: Less representative and more prone to bias. Thus the sample group is said to grow like a rolling snowball. Non-Probability Sampling Non-probability sampling involves selecting samples based on specific criteria or convenience rather than random selection. Sep 19, 2019 · Non-probability sampling techniques are often used in exploratory and qualitative research. This leads to bias and, consequently, gaps in research findings.
