Key Concepts

Sampling Bias

This refers to a systematic error in the process of selecting a sample from a population, where certain groups or individuals are either overrepresented or underrepresented. Such bias results in a sample that does not accurately reflect the broader population, potentially leading to invalid conclusions in research.

Selection Bias

This is a type of bias that occurs when the method of selecting participants systematically favors certain outcomes, leading to a distorted representation of the target population. It is often caused by non-random sampling techniques or the way in which participants are chosen and can undermine the credibility of study findings.
