Which of the following does NOT describe the population?

Question

BlackTom AI · Accepted Answer

To tackle this question, first recall the definition of the population in statistics: it is the entire set of items or individuals that are of interest for a study, i.e., all items that could potentially be included in the analysis.

Option a: 'a. Denoted by N' — This describes a common notation for population size, where N stands for the number of elements in the population. This is a characteristic of the population concept, so this option describes the population.

Option b: 'b. All items of interest' — This is a direct description of what constitutes the population: every item or individual that is of interest in the study. This indeed describes the population.

Option c: 'c. Total group of interest' — This phrase is another way to express the idea of the population: the entire group we care about for inference. This also describes the population.

Option d: 'd. A subset of the sample' — Here the phrase refers to a portion drawn from the sample, not the whole population. A subset of the sample is still a part of the sample, which by definition is not the entire population. This option does not describe the population and instead describes a part of the sampling process.

In summary, the statements in options a, b, and c align with the concept of a population, whereas option d does not and thus is the incorrect descriptor of the population.
