Just answer the question as thorough as possible, do a good job not a have assed job Sampling is important when a researcher needs to identify a sample from a population. Two sampling methods include simple random sampling and systematic sampling. Simple random sampling is a sampling technique that assigns equal probability to every member of a target population. Members are chosen at random, with no specific formula. In systematic random sampling, members of a large target population are selected according to a random starting point and a fixed periodic interval called a sampling interval. The sampling interval is arrived at by dividing the population by the desired sample size. Would you link the types of research designs you mentioned above to specific nursing research projects and talk about why the specific design was chosen for a specific project?
