In written or oral surveys, a relatively small group, called the <u>survey sample</u>, is used to draw conclusions about a larger group, called the <u>target population</u>.
A survey is a set of questions used in human subject research with the goal of gathering specific information from a target population. Surveys can be carried out via the phone, by mail, online, at street corners, and even in shopping centres.
A sample survey is one that is conducted using a sampling technique, meaning that just a section of the population is surveyed. The Oxford Dictionary of Statistical Terms, published by Oxford University Press in 2003 under the editorship of Yadolah Dodge, is a source publication from the International Statistical Institute.
