Population is a term used in mathematics, statistics, and other fields to refer to the total number of individuals in a given group or area. In the context of statistics, population refers to the entire set of people or objects that a researcher wants to study or draw conclusions about.
When discussing population, it is important to differentiate between two types: the finite population and the infinite population.
1. Finite Population: A finite population is one that has a specific and countable number of members. For example, if you wanted to collect data on the number of students in a school, the population would be finite because there is a fixed number of students that can be counted. In this case, the population is small enough that it can be measured and analyzed in its entirety.
2. Infinite Population: An infinite population is one that is too large or continuously changing, making it impossible to count or measure every member. Examples of infinite populations include all humans in the world or all trees in a forest. In these cases, it is not feasible to gather data on every individual, so researchers choose to study a sample of the population instead.
When conducting statistical analyses or making inferences about a population, it is often impractical or impossible to collect data from every member of the population. In these situations, researchers rely on statistical sampling techniques to select a representative subset of the population known as a sample. By studying the sample, they can make generalizations and draw conclusions about the larger population.
In summary, population refers to the total number of individuals in a group or area. It can be finite or infinite, and when studying a population, researchers often use statistical sampling techniques to gather data and make inferences about the entire group.
