We have new instructional and practice content for standards in topics like study design, probability distributions, and expected value.

The course is now better aligned to Common Core high school statistics and probability standards.For example, we now have practice content on calculating expected value and more practice content on interpreting what expected value does (and doesn’t) say. The course now covers a broader range of topics at a greater depth than before. There are a lot of new videos, exercises, and articles in the course that weren’t there before. We completely revamped the course with our freshest and best content.

Here’s what I’m most excited about when it comes to the new look of our High school statistics course: As a former high school math teacher, I’ll admit that teaching statistics was always my favorite, so it was a real treat to spend my time improving this course for you. Hello! I’m Jeff on the math content team here at Khan Academy, and I’m happy to share that we’ve updated our High school statistics course to make it better than ever. I'll let our Math team tell you more! High School Statistics Random sampling vs.Today we've released substantial updates to our AP®︎/College Statistics and High School Statistics courses. Happy learning! Content AddedĬonditional distributions and relationships You can see exactly what content items we’ve added and removed below.

Most people will see a much smaller Mastery percentage change. With this specific course update, we expect that Mastery percentages will change by a maximum of 65%. This change would change your Mastery percentage from 90% to 82%. For example, if you mastered 90 out of 100 skills in a course, and we added 10 new skills, your mastery skill count would then be 90 out of 110. When we add new content and remove old content, Mastery percentages often change because the number of available skills changes. One consequence of adding this new content is that it may impact learners’ Mastery percentages. We are excited to share that we've made significant enhancements to our High School Statistics course.
