Description: Judgmental sampling is a non-probabilistic sampling technique in which the researcher uses their own judgment to select the subjects that will be part of a study. This methodology relies on the experience and knowledge of the researcher about the topic in question, allowing them to identify participants who are most relevant or representative for the study’s objective. Unlike probabilistic sampling methods, where each individual has a known probability of being selected, judgmental sampling does not guarantee that all subjects have the same opportunity to be chosen. This technique is particularly useful in situations requiring a more qualitative approach, such as exploratory studies or research where the population is difficult to access. The main characteristics of judgmental sampling include flexibility in subject selection, the ability to obtain rich and detailed information, and the capacity to adapt to the specific needs of the study. However, it also presents disadvantages, such as the risk of bias in participant selection, which can affect the validity and generalizability of the results. Despite its limitations, judgmental sampling remains a valuable tool in the field of research, where the quality of information may be more important than quantity.
