What is random sampling?

Random sampling is a scientific method used in research to ensure that every member of a population has an equal chance of being selected for a study. This approach is fundamental because it helps to eliminate biases and makes the sample representative of the larger population. When researchers use random sampling, it allows for generalizations to be made about the population based on the characteristics observed in the sample.

The notion that random sampling includes every member equally is crucial because it supports the validity of statistical analyses and helps in drawing unbiased conclusions. In contrast, targeting specific populations or allowing for unequal chance selection can lead to skewed data and can obscure the true characteristics of the overall group being studied. Likewise, the idea that random sampling is limited to small groups is incorrect; it can be applied to large populations as well, ensuring that all individuals within that population have a fair opportunity to be included in the sample.
