Advantages and Disadvantages of Samplin

Disadvantages of sampling The reliability of the sample depends upon the appropriateness of the sampling method used. The purpose of sampling theory is to make sampling more efficient. But the real difficulties lie in selection, estimation and administration of samples Pros and Cons of Different Sampling Methods. Conversations about sampling methods and sampling bias often take place at 60,000 feet. That is, researchers like to talk about the theoretical implications of sampling bias and to point out the potential ways that bias can undermine a study's conclusions Because of its simplicity, systematic sampling is popular with researchers. Other advantages of this methodology include eliminating the phenomenon of clustered selection and a low probability of.. Some of the disadvantages are: Since choice of sampling method is a judgmental task, there exist chances of biasness as per the mindset of the person who chooses it. Improper selection of sampling techniques may cause the whole process to defunct. Selection of proper size of samples is a difficult job
