What is another name for general sampling?
1) Targeted sampling
2) Random sampling
3) Survey sampling
4) Lack of sampling
The Correct Answer and Explanation is :
The correct answer is 3) Survey sampling.
Explanation:
General sampling refers to methods used to select a subset of individuals or items from a larger population to estimate characteristics of the whole population. In research, this is crucial for making inferences without needing to study every individual. One of the most common forms of general sampling is survey sampling, which encompasses various techniques aimed at gathering information from a population through surveys.
Survey sampling can take several forms, including random sampling, stratified sampling, and systematic sampling. In random sampling, every individual in the population has an equal chance of being selected, which helps to eliminate bias and allows for the generalization of results. Stratified sampling involves dividing the population into distinct subgroups or strata (e.g., age, income level) and sampling from each stratum to ensure that all segments of the population are represented. Systematic sampling involves selecting every nth individual from a list or population, which can be simpler and more convenient than random sampling.
The use of survey sampling is prevalent in various fields, including market research, social sciences, and public health. It allows researchers to gather valuable data efficiently, saving time and resources while still yielding results that can provide insights into the population’s behavior, preferences, or health outcomes.
In contrast, terms like “targeted sampling” refer to specific methods where samples are chosen based on particular characteristics, while “lack of sampling” is not a recognized term in statistical methodology. Therefore, survey sampling encompasses the broader techniques of general sampling, making it the correct answer in this context.
