Answer:
In statistics, a population is the entire pool from which a statistical sample is drawn. A population may refer to an entire group of people, objects, events, hospital visits, or measurements. A population can thus be said to be an aggregate observation of subjects grouped together by a common feature.
Unlike a sample, when carrying out statistical analysis on a population, there are no standard errors to report—that is, because such errors inform analysts using a sample how far their estimate may deviate from the true population value. But since you are working with the true population you already know the true value.
Explanation:
In ecology, a population consists of all the organisms of a given species that live in a particular area.
Two important measures of a population are population size, the number of individuals, and population density, the number of individuals per unit area or volume.
