Sampling


Sampling is the process of selecting a subset of individuals or observations from a larger population to estimate or infer characteristics about the whole population. In data science, sampling is a crucial technique used to collect data from a representative subset of a larger dataset. Sampling can be done in various ways, including random sampling, stratified sampling, cluster sampling, and systematic sampling. The choice of sampling method depends on the research question, the size of the population, and the available resources. Sampling is used in various data science applications, including market research, opinion polls, medical studies, and quality control. The accuracy and reliability of the results obtained from a sample depend on the sampling method used and the size of the sample.
