Sampling is the process of selecting a representative subset of a population to study in a research investigation. The goal of sampling is to ensure that the sample is representative of the larger population and can be used to draw valid conclusions about the population as a whole. There are various methods of sampling, such as simple random sampling, stratified sampling, cluster sampling, and convenience sampling. The choice of sampling method depends on the research question, the size and diversity of the population, the resources available, and other practical considerations. Snowballing is a non-probabilistic sampling method where existing study participants recruit others from their network, which is useful for studying hard-to-reach populations but may introduce bias. Delimitation refers to defining the scope and boundaries of a study. Random assignment is a method of assigning study participants to different treatment or control groups in an experimental study to ensure that the groups are comparable on all relevant variables except for the treatment.
