Means comparisons using the Dunnet test
Dunnet tests weather means are different from the mean of the control
(The common control in our system is the variety M82). This multiple comparison test takes in consideration
the number of independent comparisons that are being made, under the assumption that there are a number of
random mistakes and this number is proportional to the number of comparisons being made.
Under this assumption, the confidence level is adjusted to the number of comparisons.
