Key Concepts

Simple Random Sampling

Simple random sampling is a fundamental sampling technique in which every member of the population has an equal chance of being selected. This method is valued for its ability to produce unbiased estimates and representative samples if carried out correctly. However, it often requires a complete and accurate list of the population, known as a sampling frame, to implement effectively.

Sampling Frame

A sampling frame is the complete list or database of all individuals in the target population from which a sample is drawn. In the context of nationwide surveys, especially those spanning diverse groups like the voting-age population, building an accurate sampling frame can be exceptionally challenging. Without a reliable frame, achieving a true simple random sample may be impractical or lead to sampling bias.

Survey Sampling

Survey sampling is the process of selecting a portion of a population to represent the whole in order to make inferences about the entire group. It includes a variety of sampling methods such as simple random sampling, stratified sampling, and cluster sampling. The choice of method depends on factors like the survey’s objectives, available resources, and the nature of the population, which directly affects the survey's overall reliability and validity.
