# Thread: How to interpret Tukey's Test results?

1. ## How to interpret Tukey's Test results?

I know how to interpret plot (a) but I am confused about plot (b) with the Tukey's Results... they don't seem like any of the results i've found online and I'm having trouble understanding the information gained from the plot

The way I learned it is that the means that are joined with bars are not significantly different from one another. From (b), I would interpret it as saying mu(-1,1) < mu(-1,-1) < [mu (1,-1) & mu(1,1)] which means that mu(1,1) and mu (1,-1) are not significantly different from one another (since joined by the line) but that they hold the spot of "largest" with mu (-1,-1) being significantly smaller located in the "middle" spot, with mu (-1,1) being significantly smaller than the other groups and occupying the "smallest" spot.

Really short: no significant difference between the two on the right joined by a line, but these two are significantly larger than the middle and left most means. The middle mean is significantly larger than the left most mean (-1,1).

Hope this is somewhat clear.
