Key Concepts

Biased Sample

A biased sample in statistics refers to a sample that does not accurately represent the population from which it is drawn. This occurs when the method of collecting the sample systematically favors certain outcomes, leading to a distortion in the data and conclusions that cannot be reliably generalized to the broader population.

Sampling Bias

Sampling bias is the process or result of the bias introduced during the sample selection. It happens when there are systematic errors in a sample due to non-random selection methods, which can cause some members of the population to be overrepresented or underrepresented compared to other members.

Representativeness

Representativeness is the degree to which a sample reflects the characteristics of the entire population. Ensuring that a sample is representative is crucial because non-representative (biased) samples can lead to misleading or invalid conclusions about the population as a whole.
