Why is sampling bias is a problem?

Sampling bias is a problem because it leads to results that are not representative of the overall population, skewing the findings and compromising the validity of conclusions drawn from the data. This can occur when certain groups are overrepresented or underrepresented in a sample, resulting in misleading insights that can affect decision-making and policy formulation. Consequently, the conclusions may not accurately reflect the realities of the entire population, leading to flawed interpretations and potential negative outcomes.
