Sampling

Sampling is a statistical technique used to select a subset of individuals from a larger population to draw conclusions about the whole group. This method is essential when studying an entire population is impractical due to constraints like time, cost, or feasibility. By analyzing a representative sample, researchers can estimate characteristics and make inferences about the population. There are two main types of sampling techniques: probability sampling, where every unit has an equal chance of selection, and non-probability sampling, where this is not guaranteed. Understanding these methods is crucial for accurate data analysis and decision-making.
