AP Statistics Sample Surveys Bias and Sampling Methods. Types of Sampling Non-Probability Sampling. In this type of population sampling, members of the population do not have equal chance of being selected. Due to this, it is not safe to assume that the sample fully represents the target population. It is also possible that the researcher deliberately chose the individuals that will participate in, Methods of sampling. To ensure reliable and valid inferences from a sample, probability sampling technique is used to obtain unbiased results. The four most commonly used probability sampling methods in medicine are simple random sampling, systematic sampling, stratified sampling and cluster sampling..

Accidental sampling (sometimes known as grab, convenience or opportunity sampling) is a type of nonprobability sampling which involves the sample being drawn from that part of the population which is close to hand. That is, a population is selected because it is readily available and convenient. It may be through meeting the person or including With stratified sampling (and cluster sampling), you use a random sampling method With quota sampling, random sampling methods are not used (called "non probability" sampling). As a very simple example, let's say you're using the sample group of people (yellow, red, and blue heads) for your quota sample. The top level of people is much closer
