  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

  6. each other?
