NURS 3151 Strengths and Weaknesses of The Sampling Method

 

Selection of the appropriate sample is critical to the
reliability and validity of research methodology. The sample must be
representative of the population that is being studied. Researchers often report
both the inclusion and exclusion criteria for the sample. There are many
different methods for selecting a sample and random sampling provides the high
control of outside variables but is often difficult to utilize in many studies.

For this Discussion, please review the following:

For this assignment, read the article by Labrague, L. &
McEnroe-Petitte, D. (2016). Influence of music on preoperative anxiety and
physiological parameters in women undergoing gynecologic surgery. Clinical
Nursing Research, 25(2), 157-173, listed in the resource section for this week.

By Day 3

Prepare a 350-word post discussing the strengths and
weaknesses of the sampling method used in this study and if the sampling method
promoted reliable and valid results. Include in the discussion if there is
anything the researcher could have done to improve the sampling process.

Note: Post a three paragraph (at least 350 words) response.
Be sure to use evidence from the readings and include in-text citations.
Utilize essay-level writing practice and skills, including the use of
transitional material and organizational frames. Use the writing resources to
develop your post.

By Day 7

In statistics, a simple random sample (or srs) is a subset of individuals (a sample) chosen from a larger set (a population) in which a subset of individuals are chosen randomly, all with the same probability. In sirs, each subset of k individuals has the same probability of being chosen for the sample as any other subset of k individuals. A simple random sample is an unbiased sampling technique. Simple random sampling is a basic type of sampling and can be a component of other more complex sampling methods.
