Experience 1 - Sampling Methods

Introduction to Statistics: Sampling Methods



We live in a society where important decisions are made by popular opinion and reliable estimates are worth a lot of money. It is often not practical to collect data for an entire population, for example the US census costs $13 billion to complete. In most situations sampling methods are used and they comprise the first step in our inferential statistics procedure.

Learning Objectives

  • Learn the basic terminology used in the study of Statistics.
  • Understand the common sampling methods (cluster, convenience, random, stratified, and systematic)

Performance Criteria

  • The learner will use the correct vocabulary when communicating with the instructor or other students about Statistics.
  • The learner will identify and justify appropriate sampling methods for hypothetical studies.
  • The learner will collect samples using the five common methods and provide explanations for how they were determined.

Note: The simulations require updated JAVA, see Get your computer ready in the Do This First folder.

Run the simulation to see the differences between simple random and stratified sampling

Note: Always begin by familiarizing yourself with the terminology for the experience.

Video Models

Models are high quality work that should be used as examples when completing the applications. These are videos made by the instructor showing how to use technology to complete the processes in the experience. Make sure to report any errors.
