Question

A personality psychologist is interested in studying the characteristics of people who report being abducted by UFOs. She finds several people in an online support group for UFO abductees who agree to participate in her study and she asks each of them if they can provide the names and contact information of other people who have also been abducted by UFOs. Upon contacting these new participants, she asks them to refer her to even more people they may know who have been abducted. This is an example of what kind of sampling

Answer 1

Cluster sampling

Step-by-step explanation:

Cluster sampling can be understood as the sampling strategy used in statistics whenever a statistical community has mutually homogeneous but internally diverse groups. It's frequently utilized in market research. The whole population is split into such categories (known as clusters) in just this sampling strategy and a basic randomized representative of the groupings is chosen.
