Probability samples are those that are selected with a known probability of each element being included in the sample, such as simple random sampling, stratified sampling, and cluster sampling. Non-probability samples are those that are selected without a known probability of each element being included in the sample, such as convenience sampling, snowball sampling, and purposive sampling. These two types of samples have different strengths and weaknesses and are used in different research contexts.
