Quick Summary

In statistics, a population proportion refers to the fraction of individuals or elements within a larger group (the population) that possess a specific characteristic. Because it's often impractical to survey an entire population, a smaller group, known as a sample, is studied. The characteristics of this sample, such as the sample proportion, are used to estimate the characteristics of the entire population through a process called statistical inference.12

Statisticians use two main types of estimates:
* Point estimates provide a single value as the best guess for the population parameter.
* Interval estimates, also known as confidence intervals, offer a range of values and a degree of confidence that the true population parameter falls within that range.12
