# All Pairwise Comparisons among Means: Recapitulation
and Recommendations (3 of 3)

Next section: Example calculations
If the null hypothesis were accepted for the two nonsignificant comparisons,
you would conclude that:

- µ
_{1} ≠ µ_{3}

- µ
_{1} = µ_{2} and

- µ
_{2} = µ_{3}

which is clearly not possible. The proper conclusion is that either µ

_{1} ≠ µ

_{2}, µ

_{2} ≠ µ

_{3} or
neither µ

_{1} nor µ

_{3} is equal to μ

_{2}.
More data are needed to decide among these three alternatives.
