Non-random sampling involves selecting samples based on the researcher’s judgment or convenience rather than at random. This technique is commonly used when it is difficult or costly to select a random sample from a large population. Examples of non-random sampling include convenience sampling, where samples are chosen based on their availability, or judgment sampling, where the researcher selects a sample they believe to be representative. While non-random sampling is quicker and cheaper, it carries a higher risk of bias because it doesn’t give every member of the population an equal chance of selection.
