Content Updates - September 2020


We're always working to improve Khan Academy content! Here's what changed this month:

AP Statistics

We’re thrilled to let you know about the addition of new content to our AP Statistics course, providing even more alignment to the updated Course and Exam Description from College Board. Here are some of the topics that we now cover:
  • Mosaic plots
  • Influential points, outliers, and high-leverage points in scatterplots
  • Systematic random sampling
  • Prospective and retrospective studies
  • Mean and standard deviation of geometric distributions
  • Sampling distributions for differences between two means or proportions
We’ve also made smaller edits to some of our existing exercises to improve alignment based on changes in the Course and Exam Description.
