Convenience Sampling
sampling strategy when a researcher selects subjects that are easily accessible to
participate in a study
Convenience Sampling
a nonprobility method of selecting a sample that includes subjects who are
conveniently available to the reseracher.
Bracketing

and setting them aside by demonstrating awareness of potential suppositions of
the researcher.
Audit trail
Detailed documentation of sources of information, data, and design decisions
related to a qualitative research study.
Triangulaton
A means of enhancing credibility by cross-checking information and conclusions,
using multiple data sources, using multiple research methods or researchers to
study the phenomenon, or using multiple theories and perspectives to help
interpret the data.
attrition
A threat to internal validity resulting from loss of subjects during a study.
bar chart

data set.
Mode

data set.

interpret the data.
Inter-rater reliability:
The extent to which an instrument is consistent across raters, as measured with a
percentage agreement or a kappa statistic.
snowball sampling
convenience sampling that violates both randomness and independence. The
