What is random sampling?

Random sampling is a technique that ensures every individual in a population has an equal opportunity to be selected as part of the sample. This method is critical in research as it helps to eliminate biases that might affect the results, allowing for the generalization of findings to the larger population. By giving each individual the same chance of being selected, random sampling contributes to the reliability and validity of the study outcomes.

In contrast to methods that select subjects based on availability, demographics, or comparing results from different studies, random sampling focuses specifically on the selection process itself, making it unrelated to those alternative methods. This approach is fundamental in fields such as statistics and social sciences, where obtaining an unbiased representation of a population is essential for accurate analysis and conclusion drawing.
