15.1 What is meant by sampling?
Sampling is the process of selecting a number of study subjects from a defined study population (i.e. the population being investigated). In most research projects it is not possible to include all the study population in the research design. Therefore, you need to look at a sample of individuals who will give you the necessary information that you can then apply to everyone in the study population. As you have already learned in Study Session 14, it is first necessary to define the study population being investigated and only then can you begin to think about how you might take a sample from it.
- Why do you think that sampling may be necessary if you want to study health issues in your locality?
As you have learned in previous study sessions, study variables can be categorised as quantitative and qualitative, and the data you collect in a research study may also be categorised in this way. Your sampling methods should follow different techniques depending on whether the data is quantitative or qualitative. In this section you will learn about sampling methods for both types of data, and also how to avoid bias in the sampling process.
- How might bias arise in data collection? (You may want to refer back to Study Session 12.)

The critique of qualitative research requires the use of different standards and criteria than are used for quantitative research. The great diversity of available qualitative methods can make evaluation or critical appraisal difficult for consumers of research who are less familiar with these methods. The current paper suggests that the following guidelines be used when a qualitative research paper is being examined: the topic must be appropriate for qualitative enquiry; the specific qualitative research method chosen must “fit”; the literature reviewed should be consistent with the method chosen; there should be ample description of informants or participants, context, and researcher; appropriate methods for information gathering and information analysis should be employed; the conclusions should be sound; and, the research must have some importance and relevance
