Sampling Procedure Research Paper

The main types of probability sampling methods are simple random sampling, stratified sampling, cluster sampling, multistage sampling, and systematic random sampling.

The key benefit of probability sampling methods is that they guarantee that the sample chosen is representative of the population.

Non-probability sampling methods offer two potential advantages - convenience and cost.

The main disadvantage is that non-probability sampling methods do not allow you to estimate the extent to which sample statistics are likely to differ from population parameters.

This ensures that the statistical conclusions will be valid.

There are many ways to obtain a simple random sample. Each of the N population members is assigned a unique number.These include probability and non probability sampling.Probability Sampling Procedures In probability sampling, everyone has an equal chance of being selected.The list includes 2,500 Ford buyers, 2,500 GM buyers, 2,500 Honda buyers, and 2,500 Toyota buyers.The analyst selects a sample of 400 car buyers, by randomly sampling 100 buyers of each brand. (A) Yes, because each buyer in the sample was randomly sampled.The sampling strategy that you select in your dissertation should naturally flow from your chosen research design and research methods, as well as taking into account issues of research ethics.To set the sampling strategy that you will use in your dissertation, you need to follow three steps: (a) understand the key terms and basic principles; (b) determine which sampling technique you will use to select the units that will make up your sample; and (c) consider the practicalities of choosing such a sampling strategy for your dissertation (e.g., what time you have available, what access you have, etc.).(D) No, because every possible 400-buyer sample did not have an equal chance of being chosen.(E) No, because the population consisted of purchasers of four different brands of car. A simple random sample requires that every sample of size is equal to 400) has an equal chance of being selected.If there is more about sampling that you would like to know about, please leave feedback.
