My colleague asked me use sampling technique. What are the advantages of using this technique?
The main advantage of sampling technique is a low risk factor. Also, it eliminates clustered selection. Clustered selection, is a phenomenon where randomly chosen samples are uncommonly close together. This is eliminated in systematic sampling. Random samples can deal with this, only by increasing the number of samples.
Few others advantages that were missed by name1 are easy to execute and sense of process. Systematic samples are easy to construct, execute, and compare. It also provides researchers with a degree of control and sense of process, which may be beneficial for studies with strict parameters or a narrowly formed hypothesis.
