A sampling procedure where units of the sampling frame that are similar on one or more variables (typically geographic) are organized into larger groups (i.e. clusters), and a sample of groups is sele [..]

is a form of probability sampling that involves sampling in naturally occurring clusters such as schools, households, or suburbs. In single-stage cluster sampling, a random sample of clusters is drawn and within each selected cluster either all units of analysis or a random sample of units are observed. An example of a two-stage cluster sampling is [..]

Sampling approach used in door-to-door interviewing in which “clusters” are randomly selected (e.g., a sample of city blocks) to represent a larger geographic area. Cluster sampling reduces the cost o [..]
