Statistical Sampling

A methodological approach to studying populations by selecting and analyzing representative subsets, enabling efficient and accurate inference about larger groups.

Statistical Sampling

Statistical sampling is a fundamental technique in data analysis and research methodology that enables drawing conclusions about large populations by studying carefully selected subsets. This process bridges the gap between Randomness and structured scientific inquiry.

Core Principles

Representative Sampling

The foundation of effective sampling rests on several key principles:
