Which characteristic of a research statement is missing in this statement?
"A study was conducted to evaluate whether short-term, cultural immersion, clinical experiences could effect change in cultural sensitivity and cultural self-efficacy."
Population being studied.
Identification of variables being investigated.
Possibility of empirical testing.
Independent variable.
The Correct Answer is D
The independent variable is the characteristic of a research statement that is missing in this statement. The independent variable is the variable that the researcher manipulates or controls to examine its effect on the dependent variable. The dependent variable is the variable that the researcher measures or observes to evaluate the outcome of the intervention or treatment. A research statement should clearly identify both the independent and dependent variables being investigated, as well as the population being studied and the possibility of empirical testing. In this statement, the dependent variables are cultural sensitivity and cultural self-efficacy, and the population being studied is implied to be nursing students or nurses who participate in short-term, cultural immersion, clinical experiences. However, the independent variable is not explicitly stated. It could be the type, duration, or intensity of the cultural immersion, clinical experiences, or a comparison group that does not receive such experiences. The other options are not correct because: A) Population being studied is not missing in this statement. The population being studied is implied to be nursing students or nurses who participate in short-term, cultural immersion, clinical experiences. Although it could be more specific and include the characteristics or criteria of the population, such as age, gender, education level, or ethnicity, it is not completely absent from the statement. B) Identification of variables being investigated is not missing in this statement. The variables being investigated are cultural sensitivity and cultural self-efficacy, which are clearly stated in the statement. These are the dependent variables that the researcher measures or observes to evaluate the outcome of the intervention or treatment. C) Possibility of empirical testing is not missing in this statement. The possibility of empirical testing is implied by the use of words such as "evaluate" and "effect change", which suggest that the researcher intends to collect and analyze data to answer the research question. Empirical testing means that the research question can be answered using objective and systematic methods of observation and measurement.

Correct Answer is C
Explanation
Stratified random sampling is the type of sampling method that the researcher should choose to best answer the study question. Stratified random sampling is a type of probability sampling technique that involves dividing the population into homogeneous subgroups or strata based on a relevant characteristic or variable, and then selecting a random sample from each stratum using simple random sampling or systematic sampling. The proportion of participants from each stratum can be proportional or disproportional to their representation in the population. Stratified random sampling ensures that each subgroup or stratum is adequately represented in the sample, and that the sample is more representative and generalizable to the population. In this study question, the researcher wants to compare the adherence to a daily exercise regimen between clients discharged in warmer months and those discharged in colder months from a postoperative orthopedic unit. Therefore, the researcher can use stratified random sampling to divide the population of clients discharged from the orthopedic unit after joint replacement surgery during the past 12 months into two strata based on the season of discharge (warmer months or colder months), and then select a random sample from each stratum using simple random sampling or systematic sampling.
The other options are not correct because:
Quota sampling is a type of non-probability or convenience sampling technique that involves selecting participants who meet certain criteria or quotas until the desired sample size or proportion is reached. Quota sampling does not ensure that each participant has an equal chance of being selected, and that the sample is representative and generalizable to the population. In this study question, quota sampling would not be appropriate because it would not guarantee that the clients discharged in warmer months and those discharged in colder months are randomly and representatively selected from the population.
True random sampling is a type of probability sampling technique that involves selecting participants from a list or population using a random number generator or table. True random sampling ensures that each participant has an equal chance of being selected, and that the sample is representative and generalizable to the population. However, true random sampling does not ensure that each subgroup or stratum is adequately represented in the sample, and that the sample is more representative and generalizable to the population. In this study question, true random sampling would not be appropriate because it would not guarantee that the clients discharged in warmer months and those discharged in colder months are equally and proportionally represented in the sample.
Convenience sampling is a type of non-probability or convenience sampling technique that involves selecting participants who are easily available and accessible to the researcher. Convenience sampling does not ensure that each participant has an equal chance of being selected, and that the sample is representative and generalizable to the population. In this study question, convenience sampling would not be appropriate because it would not guarantee that the clients discharged in warmer months and those discharged in colder months are randomly and representatively selected from the population.
