Key Terms:
  • statistics
  • mean
  • distribution
  • probability
  • sample
  • risk
  • model
  • conceptual model
  • mathematical model
Main Ideas:
  • Scientists use statistics to classify, organize, and interpret data.
  • Measures such as means and probabilities are used to describe populations and events.
  • Statistics provides a powerful tool for evaluating information about the environment.
  • Scientists use models, including conceptual and mathematical models, to understand the systems they study.
