100
Groups that occur naturally in the population are sampled.
What is cluster sampling?
100
Selection of cases that are most typical, normal, or representative of the group of cases under study.
What is typical case sampling?
100
Independent sampling procedures in which probability sampling is used for the quan strand and purposive sampling is used for the qual strand.
What is parallel mixed sampling (basic mixed methods sampling technique)?
100
Will the purposive and probability sampling lead to the collection of data focused on the qual or quant questions under investigation?
What is "your sampling strategy should stem logicially from the reserach questions and hypotheses"?
100
A convenience sample in shich individuals willingly agree to participate in a study.
What is a volunteer sample?
200
A random sample is drawn and then various subgroups of a population are sampled.
What is stratefied random sampling?
200
Selection of cases near the ends of the distribution of cases of interest.
What is extreme/deviant case sampling?
200
Identification of a subgroup of the population of interest and then selection of cases from each subgroup in a purposive manner.
What is stratefied purposive sampling?
200
Are you violating any of the established rules of any of the sampling techniques?
What is "follow the assumptions of the probability and purposive sampling techniques"?
200
Selection of informative cases that represent a phenomen of interest intensively (but not extremely).
What is intensity sampling?
300
Each unit in the population has an equal chance of being included in the sample and the inclusion of units are made independently of one another.
What is random sampling?
300
Well-known sampling technique that invovles using participants to identify additional cases who might be interested in participating in the study.
What is snowball sampling?
300
Taking a random sample of a small number of units from a much larger target population.
What is purposive random sampling (baseic mixed methods sampling technique)?
300
Is your sampling strategy inherently practical?
What is " your sampling strategy should be feasible and efficient"?
300
Unique case sampling procedures that involves selecting politically significant or sensitive cases for study.
What is sampling of politically important cases?
400
Sampling units are selected using more than one probability technique.
What is multiple probability techniques?
400
Identifying a single case representing a phenomenon that previously was inaccessible to scientific investigation.
What is revelatory case sampling?
400
Results from the first sample inform selection of the second sample.
What is sequential mixed?
400
How are telling others about your sampling strategy?
What is "describe your sampling strategy in enough detail so that others can understand it and perhaps use it in future studies"?
400
Selecting cases based on the recommendation of an expert.
What is reputational case sampling?
500
A convenience sample taken from a particular environment where individuals may find it difficult not to participate.
What is a captive sample?
500
Using two or more purposive techniques.
What is multiple purposive technique?
500
Multiple sampling techniques applied at different levels to address one ore more research questions.
What is multilevel mixed?
500
Is the overall sampling strategy sufficiently focused to gather all necessary data to answer the research questions?
What is "your sampling strategy should generate thorough qual and quan databases on the research questions under study"?
500
Proportion of the units randomly selected from each stratum is the same as the proportion in the population.
What is proportional stratified random sampling?
