Pollsters construct a sample in the second step of a scientific poll to ensure that the data collected is representative of the larger population. A well-designed sample helps minimize bias and allows for accurate generalizations about the views and behaviors of the entire population. By using techniques like random sampling, pollsters can achieve a diverse and balanced representation, which enhances the reliability and validity of the poll results.

A questionnaire has little to do with sampling technique. Sampling technique is to do with who gets the questionnaire and that can be any sampling technique: the questionnaire can be sent to everyone (census), to a random sample, stratified random samples, to random samples in clusters, by quota or convenience. Or a pile of questionnaires can be left for respondents to pick up - self-selection.
