Qualitative research methods - a data collectors field guide - this comprehensive, detailed guide describes various types of sampling techniques and provides examples of each, as well as pros and cons. An important issue influencing the choice of the most appropriate sampling method is whether a sampling frame is available, that is, a listing of all the units that compose the study population if a sampling frame does exist or can be compiled, probability sampling methods can be used.

This approach can make sampling easier, but you will need to spend some time justifying some of your criterion later in your research however as with all things there are disadvantages also, the main issue i have found in the past, especially with my undergraduate students is the researcher bias.

The process of sampling complete groups or units is called cluster sampling where there is sub-sampling within the clusters chosen at the first stage, the term multistage sampling applies. After sampling, participants are usually randomly allocated to the intervention or control group (randomization) 3 although randomization is a probabilistic process to obtain two comparable groups (treatment and control), the samples used in these studies are generally not representative of the target population.

In probability sampling it is possible to both determine which sampling units belong to which sample and the probability that each sample will be selected the following sampling methods are examples of probability sampling: of the five methods listed above, students have the most trouble.
