Question

Quizplus · Accepted Answer

The researcher has employed purposive sampling, as they have targeted a specific group of individuals (youngsters leaving the restaurant) for their opinions on the food. This is not a random sampling technique as the selection of individuals is not based on chance, but rather on a particular characteristic (leaving the restaurant). Stratified random sampling and cluster sampling are also not applicable here, as the researcher is not dividing the population into subgroups or selecting groups of individuals based on their proximity to each other.
