NUR 4165 - Exam 2 Questions With Correct
Answers
Which type of sampling is most vulnerable to bias?
| | | | | | | |
Convenience sampling |
Rationale: Although it is the most widely used approach for quantitative
| | | | | | | | | | |
researchers, convenience sampling is the most vulnerable to sampling
| | | | | | | | |
biases. The problem with convenience sampling is that people who are
| | | | | | | | | | |
readily available might be atypical of the population.
| | | | | | |
Tell whether the following statement is True or False.
| | | | | | | |
Stratified random sampling is associated with a larger sampling error,
| | | | | | | | | |
but it is more efficient.
| | | |
False
Rationale: Stratified random sampling enhances representativeness;
| | | | | |
cluster sampling is associated with a larger sampling error but is
| | | | | | | | | | |
considered more efficient. | |
, What is a major advantage of using a questionnaire?
| | | | | | | |
Lower cost |

| | | | | | |
Which procedure would be classified as an in vivo biophysiological
| | | | | | | | | |
measure?
Body temperature
|
Rationale: In vivo measures are those performed directly within or on
| | | | | | | | | | |
living organisms, such as blood pressure, body temperature, and vital
| | | | | | | | | |
capacity measurements. Tissue biopsy, blood glucose level, and
| | | | | | | |
bacterial culture are examples of in vitro measures.
| | | | | | |
What process is associated with descriptive phenomenology?
| | | | | |
Bracketing
Rationale: Descriptive phenomenology involves four steps, the first of
| | | | | | | | |
which is bracketing. Emic perspective and fieldwork are associated with
| | | | | | | | | |
