Sampling issues are critical in research design, impacting the validity and generalizability of results. Two primary sampling methods are probability and nonprobability sampling.
Probability Sampling: This method involves random selection, ensuring that every individual in the population has a known and equal chance of being selected. Types include simple random sampling, stratified sampling, cluster sampling, and systematic sampling. The primary advantage is representativeness, enhancing the generalizability of findings. However, it requires a complete list of the population and can be resource-intensive.
Nonprobability Sampling: Here, the selection process is non-random, and individuals do not have an equal chance of being chosen. Methods include convenience sampling, judgmental (purposive) sampling, quota sampling, and snowball sampling. Nonprobability sampling is easier and cheaper but risks bias and reduced generalizability, as the sample may not accurately reflect the population.
Number of Subjects: The sample size significantly affects the study’s power and precision. Larger samples generally provide more accurate estimates and enhance the ability to detect true effects, reducing the margin of error. However, practical constraints like time, cost, and feasibility often limit the sample size. Small samples might lead to unreliable results and reduced statistical power, increasing the risk of Type II errors (failing to detect a true effect).
In summary, researchers must carefully consider sampling methods and size to balance feasibility and the validity of their findings.

What will happen to the readmission rate of patients with congestive heart failure if they receive strict follow up from nurses versus no follow up care within 30 days?
Please locate an academic nursing journal article related to congestive heart failure readmissions and follow up after discharge. Using the article selected, construct a critique of the article, 7-8 pages (including cover page and references).
· identify the problem statement or statement of purpose of the article
· describe the participants being studied, stating inclusion and exclusion criteria
· discuss the sampling issues, such as probability or nonprobability and number of subjects used
· identify the study setting—where data collection occurred
· discuss informed consent—whether the participants were fully informed, how their consent was obtained, and any other ethical considerations
· identify the hypothesis or research question
· identify the research design—for example, experimental or nonexperimental; descriptive, exploratory, explanatory, or predictive?
· identify research variables, both independent and dependent
· comment the on article’s literature review—how the study data were analyzed (what statistical measures were used)
· describe the results of the study and appropriateness of the methods used; include study limitations
· accurately critique comments on level of evidence used, nursing theory, and implications for nursing practice or research
· discuss how the research findings can be applied to the clinical area
