Sampling Theory
Sampling Theory is a statistical concept that involves selecting a subset of individuals or items from a larger population to make inferences about that whole group. Instead of studying the entire population, which can be impractical or impossible, researchers collect data from a smaller sample. By analyzing this sample, they can estimate characteristics, trends, or behaviors of the entire population. Proper sampling methods ensure that the sample accurately reflects the population, reducing bias and improving the reliability of the results. This process is crucial in fields like survey research, quality control, and scientific studies.

Sampling theory is a statistical approach used to draw conclusions about a large population by examining a small, representative subset of it. Instead of surveying everyone, researchers select a sample that reflects the population's characteristics. This allows them to make predictions or inferences about the entire group based on the sample's findings. Proper sampling minimizes bias and ensures that the results are reliable. In essence, it provides a practical way to gather insights without needing to interact with every individual in a population.
