AP Statistics: AP Statistics – Sampling and Experimental Design Quiz

The two areas of sampling and experimental design are always of great importance on the AP Statistics exam; there are always several multiple choice questions concerning these topics, and nearly always there is one entire free response question asking about the design of an experimental procedure or the sampling method that should be used. Make note of the difference between these two statistical activities. Sampling involves the appropriate selection of experimental units for a study or experiment, whereas experimental design is the architectural design for assigning subjects to experimental groups and the plan for collecting data from the subjects/groups.
