Disadvantages of non-probability sampling: The researcher interviews individuals who are easily accessible and available. Hence, the researcher does not have to do any extra effort or go out of the way to gather data. Thanks to the randomization of selection, the entire population receives usable observations that can offer specific insights at the individual level even though a small group (and not the entire population) was surveyed or studied. The pros of systematic sampling include: Easy to Execute and Understand . Obviously, we cannot afford to destroy all the eggs or the bullets, etc. Sampling gives more time to researcher for data collection, so it is quickly and has a lot of time for collection of inflammation. The study may be such that the objects are destroyed during the process of inspection. Advantages and disadvantages of sampling Disadvantages of sampling.

Advantages of Convenience Sampling. Less expensive; Very cost and time effective. Advantages of non-probability sampling: When a respondent refuses to participate, he may be replaced by another individual who wants to give information. Advantages of Sampling. Easy to use types of sampling methods. This advantage occurs because the sampling structure happens within specific boundaries set to reflect population groups. Detailed Information. Systematic samples are relatively easy to construct, execute, compare, and understand. This is particularly important for studies or surveys that operate with tight budget constraints. An additional task is saved for a researcher, this time can be used in conducting the study. Advantages of Sampling. It’s quicker to find samples: Referrals make it easy and quick to find subjects as they come from reliable sources.

It is also considered a fair way to select a sample from a population, since each member has equal opportunities to be selected. Another key feature of simple random sampling is the representativeness of the population. Advantages of simple random sampling. Advantages of Systematic Sampling . Control and Sense of Process . Suppose we want to inspect eggs, bullets, missiles or tires produced by some firm. Cost effective: This method is cost effective as the referrals are obtained from a primary data source. Subjects for a study are easily available within the proximity of the researcher. Greater Speed. Sampling has some advantages over doing a complete count. Reduce Cost. It is cheaper to collect data from a part of the whole population and is economically in advance. Advantages of Sampling Method. The cost for collecting data about entire population is quite high.
