Showing Revision 6 created 05/24/2016 by Udacity Robot.

  1. In lesson 11, you learned how to test for a significant difference in means
  2. between two independent samples. But in many research studies, we want to
  3. compare means from more than two independent samples. If we have three samples,
  4. we would need to do three T tests, A and B, B and C, and A and C. But what if
  5. we have four samples. How many t-tests would you need to compare all of them to
  6. each other?
