Probability and Statistics with NetLogo

  • For students in grades 7-9
  • Course Description: Students will construct a complex sample space and use computer simulations to observe empirical probability distributions based on that space. As time permits, students will also explore applications of this distribution to statistical research.
  • Course Dates: This course was offered during session III of the 2003-2004 school year
  • Location: Evanston campus
