There are three main types of qualitative research sampling. They are purposeful sampling, quota sampling and snowball sampling.
• Purposeful sampling: It is the most common sampling type. In this the participants are selected or sought after pre-selected criteria.
• Quota sampling: The researcher collects data from certain number of participants that have certain characteristics.
• Snowball sampling: It is also called as chain referral sampling. In this the participants refer the researcher to other who may participate in the study.
There are two main types of sampling for quantitative research. They are probability and non probability sampling. The main difference between these two is randomization which means giving equal opportunity to all the participants of being in the study.
• Simple random sample: selects one person randomly.
• Stratified sampling: population is divided into subgroups and participants are randomly selected from each group
• Systematic sampling: uses a specific system to select members
• Cluster random sampling: divides the population into clusters
• Multi stage random sampling: combination of one or more methods.
• Convenience sampling: members are selected on availability
• Purposive sampling: members are purposefully selected
