Question 1Probability sampling is rarely used in qualitative research because: a) Qualitative researchers are not trained in statistics b) It is very old-fashioned c) It is often not feasible d) Research questions are more important than sampling Question 2The two levels of sampling used by Savage et al. (2005) for the Manchester study were: a) Random and purposive b) Convenience and snowball c) Statistical and non-statistical d) Contexts and participants Question 3Which of the following is not a type of purposive sampling? a) Probability sampling b) Deviant case sampling c) Theoretical sampling d) Snowball sampling Question 4What is involved in "purposive sampling" for grounded theory? a) Using a random numbers table to select a representative sample of people b) Strategically selecting respondents who are likely to provide relevant data c) Deciding on a sampling strategy early on and pursuing it relentlessly d) Sampling units of time rather than individual persons Question 5What is meant by the term "theoretical saturation"? a) Deciding on a theory and then testing it repeatedly b) The point at which a concept is so well developed that no further data collection is necessary c) The problem of having used too many theories in one's data analysis d) A state of frustration caused by having used every possible statistical test without finding any significant results Question 6Generic purposive sampling can be characterized as being: a) Fixed and a priori b) Fixed and ad-hoc c) Contingent and post-hoc d) Contingent and ad infinitum Question 7The minimum sample size for qualitative interviewing is: a) 30 b) 31 c) 60 d) It's hard to say Question 8Why is an ethnographic study unlikely to use a probability sample? a) Because the aim of understanding is more important than that of generalization b) Because the researcher cannot control who is willing to talk to them c) Because it is difficult to identify a sampling frame d) All of the above Question 9Apart from people, what else can purposive sampling be used for? a) Documents b) Timing of events c) Context d) All of the above Question 10What can be generalized from a purposive sample? a) That the findings are true for broadly similar cases b) That the findings are true for the entire population c) That the opposite is true for people who are the opposite of those in the sample d) That purposive sampling is better than probability sampling What type of sampling is used in qualitative research?Purposive sampling
It is often used in qualitative research, where the researcher wants to gain detailed knowledge about a specific phenomenon rather than make statistical inferences, or where the population is very small and specific.
What is typical case sampling in qualitative research?A typical-case sample is composed by identifying and including people who can be regarded as typical for a community or phenomenon. Such a sample is used to avoid information, or worse, research findings and recommendations being rejected because they have been obtained from suspect, perhaps even deviant, cases.
What type of sampling is used in quantitative and qualitative research?While qualitative research typically involves pur- poseful sampling to enhance understanding of the information-rich case (Patton, 1990), quantitative research ideally involves probability sampling to permit statistical inferences to be made.
Why purposive sampling is used in qualitative research?Purposive sampling enables researchers to squeeze a lot of information out of the data that they have collected. This allows researchers to describe the major impact their findings have on the population.
