The design of a research study included a random sample size of 100 patients. At the end of the study, the sample size decreased to 75 patients. Which of the following should the nurse do with this change in sample size?
1. Document why the patients left the study.
2. Determine that the study is invalid and plan a different research design.
3. Plan another study using quota sampling.
4. Run the study again with purposive sampling.
Document why the patients left the study.
Rationale: Regardless of the sampling strategy used, it is essential to keep a careful record of the sampling decisions and identify how many people began the study, how many completed the study, and why subjects left the study before completing it. The nurse should not determine that the study was invalid nor plan another study using quota sampling or purposive sampling.
