Question

For the Research Sampling section summarize

1. What is sampling and why is sampling important.
2. One sampling strategy used in quantitative research.
3. One other sampling strategy that you learned.

For the Credible Nursing Practice section, summarize

1. How research can help to make nursing practice safe.
2. Why research is critical for creating an evidence-based nursing practice.

These answers need to be lenghty and not a short answer please i need at least a paragraph about research sampling and the second two questions.

Answer 1

1.Sampling is the process of selecting units like people ,organizations from a population of interest so that by studying the sample we fairly generalize our results back to the population from which they were chosen.Sampling is the basis of how we can draw the conclusions about the population with out being able to inspect the whole population.It is frequently impossible to took at the whole population ,sampling gives us a more practical way of approaching the problem.Sampling is important because observing every units often not possible or too expensive.The outcome will not be appropriate even if the sample is not properly structured.

2.Quantitative research is a structured way of collecting and analyzing data obtained from different sources.it involves the use of computational,statistical and mathematical tools to derive results.

Systematic sampling is a probability sampling.In this individuals or households are chosen at regular intervals from the sample frame.We randomly select a number to tell us where to start selecting individuals from the list.Systematic sampling is usually less time consuming and easier to perform than random sampling,But there is a risk of bias,as the sampling interval may coincide with a systematic variation in the sampling frame.

3.Simple random sampling-This is the simplest form of probability sampling .Methods to select a simple random sample as follows,

• Make a sampling frame-It is a numbered list of all the units in the population from which you want to draw a sample o use an already existing one.
• Decide the size of the sample.The feasible sample size is determined by the availability of resources like time,human resources,transport and money.
• Select the required number of sampling units,using a lottery method or a table of random numbers.

4 A qualitative researches uses research process to conduct a systematic investigation in to patient and family perspective and make recommendations based on their response that can advance the patient centered model. Findings from the qualitative studies can guide health care providers in planning and treatment approaches to patient care that meet patient needs.It improve the communication with patients about their prognosis so they can make appropriate informed decisions about their care.It will help to examine their transition of care practices.
