Describe the role of rigor in nursing research.
The extent to which nursing research methods are carefully and strictly conducted in order enhance the quality of the evidence that the study yields. This is even critical if casual inferences about relationships are of value. In addition, rigor ensures that threats to validity are minimized, assessed and considered during the study.
Discuss three sampling methods for nursing research. Include the positives and negatives of using each in nursing research.
Convenience Sampling
This method entails using available people as study participants. For example, a nurse conducting research of pregnant HIV- AIDS patients relies on convenient sample. The disadvantage of this method is that the available participants might not be representative of the population of interest with regard to critical variables.
Quota Sampling
This method involves the researcher indentifying the sample strata in a bid to determine the number required from each stratum. The researcher can ensure that various segments are represented in the sample by looking at information at the population characteristics. One advantage of using this method is that it does not require sophisticated skill, but the disadvantage is that it can present a bias sample.
3. Purposive Sampling
This method involves the researcher hand picking the study participants. The researcher can purposely select population judged to be representative of the population under study. The advantage of this method is that it is best used for experimental purposes such as presenting and evaluating newly developed instruments. On the other hand, it does not provide external means of assessing the typicalness of the participants.
