Simple random sampling is the most basic form of probability sampling. But, one must keep in mind, the fact that a researcher may or may not have the appropriate proficiency to conduct an effective sampling process. Researcher bias, also known as experimenter bias, is when the people performing the research end up influencing the results of a study. It requires no pre-planning for the selection of items. 10.

Most of them offer a margin of error that is between 3% to 6% and sometimes even higher. 3.3 Sampling technique and sample size. When the judgments are either poorly considered or ill-conceived, then this problem becomes a significant disadvantage that can provide roadblocks in the way of a final result. When researchers approach a population group with a random survey, then the margin of error on their conclusions can be significant.
