Sampling bias can lead to a systematic over- or under-estimation of the corresponding parameter in the population. Sampling bias occurs in practice as it is practically impossible to ensure perfect randomness in sampling. If the degree of misrepresentation is small, then the sample can be treated as a reasonable approximation to a random sample Determining the veracity of a parameter or hypothesis as it applies to a large population can be impractical or impossible for a number of reasons, so it's common to determine it for a smaller group, called a sample. A sample size that is too small reduces the power of the study and increases the margin of error, which can render the study
