Sampling in polling refers to the process of selecting a subset of individuals from a larger population to gather insights about the opinions or behaviors of that population. This smaller group, known as a sample, is intended to be representative of the whole, allowing pollsters to make inferences about the wider population's views. The quality of the sample is crucial; it must be randomly selected and sufficiently large to reduce bias and increase accuracy in the results. Proper sampling techniques help ensure that the poll's findings are valid and reliable.
