Notice the difference in Duncan's Multiple Range Test between the
two analyses.
Normally, the transformed means will be back transformed to the
original units after the analysis and these back transformed means can
often be slightly different from the means calculated on the original
data. The back transformation is done in reverse order of the transfor-
mation, thus, the outermost calculation is done first working inward
through the parenthesis to the innermost calculation. The back trans-
formation of the seed data is
(sin(trangerm)^2)/2*100
