Why does a nurse researcher avoid making generalizations based on the experiences of a small number of study participants?
A nurse researcher has made a generalization on the basis of the experience of a small number of participants. ... The small number of participants will increase the threat to internal validity influenced by history . C A too-small sample may inadequately represent the phenomenon and threaten valid conclusions.
What would a nurse researcher do to ensure that the study population is a homogeneous sample group of participants?
How would a nurse researcher ensure that the sample used in a quantitative study is homogeneous? ... Use eligibility criteria to limit extraneous variables relevant to the study.
What type of sampling is most at risk for sample bias?
Which type of sampling is most vulnerable to bias? Rationale: Although it is the most widely used approach for quantitative researchers, convenience sampling is the most vulnerable to sampling biases.
How could a nurse researcher’s use of a homogeneous sample weaken a research study?
How could a nurse researcher’s use of a homogeneous sample weaken a research study? ... A nurse researcher assigns subjects to experimental and control groups in such a manner that each subject in a population has an equal chance of being selected.
What is a good sample size for qualitative research?
It has previously been recommended that qualitative studies require a minimum sample size of at least 12 to reach data saturation (Clarke & Braun, 2013; Fugard & Potts, 2014; Guest, Bunce, & Johnson, 2006) Therefore, a sample of 13 was deemed sufficient for the qualitative analysis and scale of this study.
What is a good sample size for semi structured interviews?
Cresswell (2007) suggests that a heterogeneous population would require between 25 and 30 interviews, and semi- structured/in-depth interviews require a minimum sample size of between 5 and 25 according to (Kuzel, 1992 cited in Saunders, 2012; and Cresswell, 2007).

What is the weakest sampling method?
CONVENIENCE SAMPLING – Subjects are selected because they are easily accessible. This is one of the weakest sampling procedures. An example might be surveying students in one’s class. Generalization to a population can seldom be made with this procedure.
What is the strongest sampling method?
Simple random sampling : One of the best probability sampling techniques that helps in saving time and resources, is the Simple Random Sampling method. It is a reliable method of obtaining information where every single member of a population is chosen randomly, merely by chance.
What is the weakest Nonprobability sampling?
- most readily accessible subjects.
- this form of sampling has the greatest risk of bias.
- subjects tend to be self-selecting.
- this form of sampling is the weakest in terms of generalizability.
