| Analysis of Variance A significant difference
        between treatments is suggested if your calculated F
        value exceeds the tabulated F value. But this tells you
        only that you have significant differences between the
        treatments as a whole. It does not tell you which
        treatments differ from one another.  Only some degrees are freedom are
        shown. If you want an intermediate value, use the next
        lowest in the table.
