Case study uses different research methods (e.g. interview, observation, self-report questionnaire) with a single case or small number of cases. Computer simulation (modeling) Ethnography; Event sampling methodology, also referred to as experience sampling methodology, diary study, or ecological momentary assessment
For a good example of situation sampling, see this study by LaFrance and Mayo concerning the differences in the use of gaze direction as a regulatory mechanism in conversation. In this study, pairs of individuals were observed in college cafeterias, restaurants, airport and hospital waiting rooms, and business-district fast-food outlets.
Usually, participants in an IPA study are expected to have certain experiences in common with one another: the small-scale nature of a basic IPA study shows how something is understood in a given context, and from a shared perspective, a method sometimes called homogeneous sampling. More advanced IPA study designs may draw together samples that ...
Graphic breakdown of stratified random sampling. In statistics, stratified randomization is a method of sampling which first stratifies the whole study population into subgroups with same attributes or characteristics, known as strata, then followed by simple random sampling from the stratified groups, where each element within the same subgroup are selected unbiasedly during any stage of the ...
Gross examination of a kidney (right of image) with a renal oncocytoma (left of image).. Gross processing, "grossing" or "gross pathology" is the process by which pathology specimens undergo examination with the bare eye to obtain diagnostic information, as well as cutting and tissue sampling in order to prepare material for subsequent microscopic examination.
The use of tissue microarrays in combination with immunohistochemistry has been a preferred method to study and validate cancer biomarkers in various defined cancer patient cohorts. The possibility to assemble a large number of representative cancer samples from a defined patient cohort that also has a corresponding clinical database, provides ...
This method of sampling is referred to as model-based sampling inference. The second approach is the one typically used in modern stereology. Instead of relying on model assumptions about the three-dimensional material, we take our sample of plane sections by following a randomized sampling design, for example, choosing a random position at ...
Case studies are generally a single-case design, but can also be a multiple-case design, where replication instead of sampling is the criterion for inclusion. [2] Like other research methodologies within psychology, the case study must produce valid and reliable results in order to be useful for the development of future research. Distinct ...
