systematic sampling
a method of sampling that involves the division of population into smaller subgroups
stratified sampling
smaller groups
strata
a method of collecting data from a large population by dividing into smaller groups or clusters
cluster sampling
the probability of any particular member of the population be ing chosen is unknown. The selection of sampling units in this sampling is quite arbitrary, as researchers rely heavily on personal judgement.
non probability sampling
what are the types of non probability sampling
convenience sampling
snowballing sampling
quota sampling
purposive sampling
it is used whe researchers chose any willing and available individuals as participants
convenience sampling
a technique that constructs sample subgroups reflecting their proportiuonal representation in the population
quota sampling
the researchers used the first participants that o match the participant profile
snowballing sampling
it refers to intentionally selecting participants beased on their characteristics, knowledge, experiences, or some other criteria
