Question

Quizplus · Accepted Answer

Sampling bias refers to a flaw in the sampling process in which some members of the population of interest are systematically excluded or overrepresented, leading to inaccurate results. Pollsters are careful to avoid sampling bias in order to obtain a representative sample that accurately reflects the views and opinions of the larger population. A random sample is not necessarily enough to ensure representativeness, as certain segments of the population may be underrepresented even in a random sample. Margins of error and independent voters are important considerations in polling, but do not relate specifically to the sampling process.
