A nurse researcher is considering using convenience sampling to choose participants in a study. The researcher must be prepared to accept which disadvantages of this sampling method? Standard Text: Select all that apply.
 
  1. This method is rarely used in nursing research.
  2. There is a greater initial monetary cost.
  3. Results may have limited generalizability.
  4. This method requires more time for participant selection.
  5. The method usually results in a biased sample.

Question 2

The nurse researcher plans to use systematic random sampling to determine participants in a study. Which components are necessary to begin this selection? Standard Text: Select all that apply.
 
  1. Population list
  2. Sampling interval
  3. Random starting point
  4. Undetermined sample size
  5. Cluster definitions

Answer to Question 1

3, 5
Rationale 1: Convenience sampling is commonly used in nursing research.
Rationale 2: Reduced cost is a benefit of convenience sampling.
Rationale 3: The results of research on convenience sample may be generalizable only to the sample, not to the general population.
Rationale 4: Convenience sampling is used because it saves time in sample selection.
Rationale 5: Because the sample was not selected in a random manner, it is likely biased.
Global Rationale:

Answer to Question 2

1, 2, 3
Rationale 1: A list of population elements is necessary for systematic selection.
Rationale 2: A sampling interval must exist in order for systematic selection to occur.
Rationale 3: A random starting point is chosen from which the selection begins.
Rationale 4: The researcher must define the desired sample size prior to the selection.
Rationale 5: Clusters are not used in systematic random sample selection.
