  5. sample when we are comparing three or more. Let's ease our way into this idea,
  6. starting with reflecting back on how the variability of individual samples
  7. impacts the difference in means. In both of these situations, these two samples
  8. have the same means and therefore, they have the same distance between means.
  9. Nonetheless in only one of these situations are the means significantly
  10. different from each other. Which one?
