Author

Craig Bauling
Organization: Wolfram Research, Inc.
Education level

Precollege
Description

Students will learn the typical measures for data spread and apply appropriate calculations to data sets. At the end of this lesson, students will be able to compute the following:
  • Range of a Discrete Random Variable
  • Variance of a Discrete Random Variable
  • Standard Deviation of a discrete random variable

This notebook covers topics that fulfill the following NCTM standards:

  • Grades 9-12: Data Analysis and Probability: Formulate questions that can be addressed with data and collect, organize, and display relevant data to answer them
  • Grades 9-12: Data Analysis and Probability: Understand and apply basic concepts of probability
