Quick Summary

A survey is a broad treatment of a subject or a poll used to gather data. In statistics, sample survey methods focus on effective ways to collect data from a sample to make estimates or test hypotheses about a larger population. Common types include mail, telephone, and personal interview surveys, all of which often use questionnaires. Other methods involve direct observation, such as sampling accounting records.12

The goal of a survey is to obtain a representative sample. Sampling error occurs because only a portion of the population is surveyed. Probability sampling methods, where each unit's chance of being in the sample is known, allow for probability statements about sampling error size. Nonprobability sampling methods are less statistically rigorous but can be more convenient.2
