Abstract: Abstract A “population” denotes a set in which elements satisfy specific conditions, such as all people in a country, or all small cars in a country. In statistical terms, extracting part of the population is called “sampling from the population.” Instead of sampling, we sometimes say we are conducting a trial. Hence, a sample is a subset of the population. Measurements, surveys, or observations over the sample produce data. Data consist of numbers, categories, images, and text. Data can also be called realizations, observations (observed values), or measurements. The term “data set” (or dataset) is used when the plurality of the data should be emphasized. In practical data analysis, however, the distinction between the sample and the data (or dataset) is not usually important.
