A study was conducted in Israel (Kagan, Ovadia & Kaneti, 2009) to examine the relationship between nurses’ knowledge of blood-borne pathogens (BBPs) and their (a) professional behavior regarding handwashing, (b) compliance with standard precautions, and (c) avoidance of therapeutic contact with BBP-infected patients. Participants were sampled in groups. From each hospital clinical division, clinical departments (clusters) were randomly selected. Questionnaires were then distributed to all individuals (240) within the groups.
What sampling method is being applied in the study?
Select one: A. Stratified Random Sampling B. Simple Random Sampling C. Systematic Random Sampling D. Cluster Sampling
Cluster Sampling
The study utilized sample of 21 hospitalized inpatients and 34 outpatients to evaluate their health literacy levels. The inpatients were recruited from medical-surgical areas of the hospital. Outpatients were obtained from several settings, which included cardiac rehabilitation, preadmitting, and neuroscience clinics. Based on scores on the Test of Functional Health Literacy in Adults, 23% of the sample demonstrated marginal or inadequate functional health literacy. Literacy was significantly related to socioeconomic status and education.
What sampling method is being applied in the study?
Select one: A. Convenience Sampling B. Multi-stage Sampling C. Stratified random sampling D. Quota Sampling
Convenience Sampling
Quota sampling _______________ .
Select one:
A. Needs a list of all elements in the study population
B. Is based on convenience in accessing the sample population and is the non probability version of stratified sampling
C. Starts with a few individuals who then identify others to be included in the sample
D. Uses the researcher’s judgment as to the ability of the respondents to contribute to the research
Is based on convenience in accessing the sample population and is the non probability version of stratified sampling
Sampling bias may be defined as the difference between data obtained from a random sample and the data that would be obtained if an entire population were measured.
Select one:
True
False
False

Select one:
True
False
True
Validity provides answer to the research question for which it was undertaken by using appropriate methods and procedures.
Select one:
True
False
True
A researcher wishes to conduct a survey of research staff at the University of Kent, to investigate their views about proposed changes to the library opening times.
