Definition

Sampling refers to the process of selecting units or portions of a larger group that will be studied in order to answer questions about the larger group. The units can be people, water samples, ice cores, or any other appropriate object. Participants will explore the meaning of sampling and how it impacts experimental design and explore factors that define and limit sampling in the variety of projects visited during the expedition. They will consider how results from the chosen samples are used to describe the bigger target of a project's study.
