Purposeful sampling focuses on specific characteristics of a population to answer research questions, while quota sampling involves selecting individuals from a certain subgroup.

- 3. Purposeful sampling/ Purposive Sampling • is selected based on characteristics of a population and the objective of the study. • Purposive sampling is also known as judgmental, selective, or subjective sampling. • The main goal of purposive sampling is to focus on particular characteristics of a population that are of interest, which will best enable you to answer your research questions.
- 4. Quota sampling •Quota sampling requires that representative individuals are chosen out of a specific subgroup. •non-random sample
- 5. Snowballing Sampling/ Snow Ball Sampling • Snowball sampling is where research participants recruit other participants for a test or study. • It is used where potential participants are hard to find. • It's called snowball sampling because (in theory) once you have the ball rolling, it picks up more “snow” along the way and becomes larger and larger.
