In qualitative research, nonprobability sampling is used. The different types of nonprobability sampling methods include:

Convenience sampling: This type of sampling strategy is not randomized. It uses the most available things or people to include in the study. The disadvantage of this type of study is that the representation of the sample study is not an accurate representation of the population or group being examined or researched. The advantage of this study is that it is its convenience.

Quota sampling: This type of sampling involves participants or subjects that are chosen from each stratum. The disadvantage of this type is that it may not represent the generalized population but is convenient type of sampling method.

Purposive sampling: This type of sampling is used when the desired or type of population being studied is difficult to attain or locate. Its purpose is to understand or gain insight of the event or experience being studied. The focus is not on the subjects but of the event or experience.

Theoretical sampling: This type of sampling method is used in grounded theory. The data collected is from a group of participants who were chosen after conducting preliminary questions/analysis. The disadvantage of this type of study is that is can not be used for generalization of the population.
