Step 1 of 1 :

Given, the author collected sample data by randomly selecting 20 different pages from a printed version of the Merriam-Webster Dictionary and then counting the number of defined words on each of those pages.

Cluster sampling : the researcher divides the population into separate groups, called clusters. Then, a simple random sample of clusters is selected from the population.

This is a cluster sample because the author is selecting 20 different "clusters" randomly that contain subjects of all different kinds and then samples every single subject in that cluster.
