Just to further elaborate, the means that are connected by lines are not significantly 
different from each other.  If two means do not share a line, then they are 
significantly different.

Paula,

First, it's a Tukey HSD test, named after John Tukey, the statistician who
developed the procedure.

Second, the letters underneath the group labels represent "lines".  Any
two groups underscored by a common line are not different.  That is, they
constitute a "homogeneous" family.

So, groups 1 & 2 are one family.  Groups 2, 6, & 3 are another family.
Groups 3, 5, & 6 are a third family.
