Scientific polls use the mathematical laws of probability to ensure accuracy. Polls survey a random sample of the population to approximate the views of the whole group Simple random sampling gives everyone in a population an equal chance of being interviewed Because the United States is so large, national pollsters use systematic sampling to obtain a more accurate sample Sampling error refers to a poll's degree of accuracy, expressed as a percentage. Polls that survey fewer individuals have a higher sampling error
