If we run a one-way ANOVA on 4th graders, 5th graders,
and 6th graders, which of these outcomes are possibly
true?
There is a significant difference between 4th and 5th
graders, but not between 5th and 6th graders.
There is a significant difference between 5th and 6th
graders, but not between 4th and 5th graders.
There are no significant differences among any of the
grades.
All of the above are possibly true
outcomes.
