In the context of statistics, population refers to the entire group of individuals, objects, or events that we are interested in studying. It is important to differentiate between a population and a sample. A population includes all members of a specified group, whereas a sample is a smaller subset of the population that we use to make inferences about the population as a whole.
For instance, if we want to study the average height of all adults in a country, the population would consist of every adult living in that country. However, it is often impractical or impossible to gather data from every member of the population. In such cases, we select a sample, which is a small group of individuals that represent the population, and gather data from them. By studying the sample, we can make informed inferences about the entire population.
In statistics, population can also be used to refer to the total count or number of objects or events in a specific group. For example, if we want to determine the population of a certain bird species in a particular region, we would count the total number of birds in that region.
It is worth noting that population can also be used in other fields, such as biology, where it refers to a group of organisms of the same species residing in a particular area.
